Hello there, I've run a few tests with the weapons from this mod and here's what I've found; this is pretty much a general overview of the weapons and how useful they really are in practice.

(Be forewarned, this is a really long but hopefully very helpful post. Allot of what I'll say is either confirmation about what the guide on google docs says or is unmentioned in said guide. In comparing weapons I'm trying to state how they actually preform in-game in combat as opposed to the guide's descriptions and just the stat numbers on paper.)

Yunhwa
These weapons are incredibly useful against soft-body/unarmored targets but are only better-than-nothing aside from the microwave weapons against armored targets. The best use for them is dealing with animal attacks, especially small ones, and putting down targets without killing them via bleeding and the resulting pain.
One of the best weapons here for the job is the Boreas/Swarmer, shots will continue to track targets and stay active even if a target leaves the gun's maximum distance after the weapon has been fired.
Microwave Grenades are fairly effective at disabling a target for capture but you'll really only want to use them if you don't have an Aurora Microwave Cannon.

The Ice Pillar Vibrosword is by far the best melee weapon at legendary quality, easily exceding a Plasteel Longsword and maybe the only weapon suitable against a mechanoid out of all Yunhwa weapons. I have mixed results comparing it with Jotun's hammer against mechanoids but it seems to do a better job only because of how much it can disable Scythers.

Yunhwa armors speciallize in speed over most of everything else, your pawns will move much faster and be more protected but not more so than the other armors. The Nervesuit will greatly decrease weapon warmup time and greatlty increase pawn speed but lowers the player's accuracy. Unless your pawn is a champion shooter and/or has stuff that enhances accuracy, using this armor isn't that advised over others unless you truly need speed. Smart weapons from the Rimsenal Enhanced Vanilla mod actually pair very well with this armor though since they give an increased accuracy bonus that can counter the Nervesuit's accuracy debuff (I personally use this combo with the Smart Sniper Rifle, results in some very nice, speedy snipers who have yet to let me down in a fight).



Jotun
They really do pack a punch per hit but should not be given to a pawn with low shooting skill since they'll generally miss even at optimal distance unless they have a Muspell, which is basically a punchier minigun. They excell at killing mechanoids as the guide says as well as any really big animal but are not the best choice against multiple soft-body targets since you will usually want faster firing or more accuracy over the unneeded extra damage.

The Fafnir shotgun is fantastic at close range against anything however and most soft-body targets will be disabled or outright killed after one burst if it's at least an excellent Fafnir, compared to other shotguns it has a lower rof and accuracy but I think the damage makes up for it in most scenerios.

Dunder Satchel Charges can breach most walls in one or two shots and are amazing against an EMP'd mechanoid, just be sure to take out any sappers who may have this weapon as soon as possible.

The Ormbane Assault Hammer is very powerful but suffers from less swings per second, however if you have the Federation Rimsenal mod installed then no other melee weapon will shread through Feds like this one.

Jotun armors include one that speciallizes in defense, making one of your pawns kind of like a centipede, and another speciallizing in fire-support; it greatly reduces aiming time, by 100%, you can think on the implications of that yourself for a moment... and back down to earth because the armor is especially weak in melee combat so just keep that in mind.



Tisiphone
These weapons are ranged options for blunt damage, serving the sole purpose of destroying Federation pawns. In the case of Federation raids, Tisiphone weapons annihilate Fed pawns far more than any other weapon, especially the Harrower Kinetic Lance. Tisiphone's Nemesis armor also makes your pawns pretty much immune to fire or energy damage (save at the neck, which will be being changed in the future), meaning Federation pawns become the easiest thing to kill so long as you have Tisiphone arms. In fact I think asside from Jotun's Tank armor, the Nemesis Reactive Carapace has the most defense possible for power armor.
However...
Against anything aside from the Federation, Tisiphone weapons could be replaced with almost anything else, they really only excell at killing things weak to blunt and if it isn't weak to blunt then you should use a different weapon that can better take on said enemy. I'm not sure why but on paper Tisiphone seem fantastic, in actual combat however they don't really preform that much better than vanilla weapons, roughly the same in fact. They have far faster warmup times but their damage, rof and sometimes range are lacking compared to even vanilla weapons (that being said they are still capable of killing enemies when needed, they're just outshined by pretty much anything else outside of their original purpose, especially with some of the other Rimsenal mods installed).

The Oppressor Thudd Gun is unlike other shotguns: it fires a slug-like canister that explodes when it reaches its target, hitting all surrounding tiles with equal ammounts of blunt damage. It's something like a mix of a shotgun and a grenade launcher but again it's best suited for Federation pawns more than normal enemies.

If you are using the Sidearm mod with this then I suggest equipping every pawn with a Survival Knife if you can. The knife gives a bonus to global work speed and is actually a fairly effective melee weapon so there's no reason why a pawn shouldn't have this out when they are working around the colony.

Tisiphone armors excell at survival in any condition, both armors are easily capapble of keeping your pawns comfortable in either the coldest ice sheets or the hottest deserts while also possesing good defense bonuses. As stated Tisiphone's Nemesis Reactive Carapace makes heat damage almost negligable (actually a legendary RC will negate almost all heat damage). The Alecto Hazard Carapace is exceptional for environmental survival, absolutely no temperature will overcome it and it gives a 100% resistance to radiation so even a nuclear fallout is survivable.



Graydale
In comparison to all other weapons across Rimsenal mods and vanilla, Graydale is the most reliable and adaptive line of weaponry available and probably the most unique I've seen in mods. Whether a result of the coding needed to make them work or completely intentional, Graydale weapons aside from the Pistol, HSMG and Combat Blade posses no quality modifiers. This means that any of the MRS or MLS variations will always have the same stats, no possiblity of your craftsman making a poor, awful or shoddy gun but at the same time no possibility of a good, excellent or legendary one. While this may seem problematic, on a true Rimworld game run where you can't just reload a previous save to prevent your colonists from ending up with crappy equipment, this is a god-send.

Another unique traight of Graydale weapons is the MRS Carbine and the Multi-launcher can be modified with craftable modules to switch to or back from multiple types of firearms, this means that should you decide you now need a sniper rifle, an incindiery launcher, a shotgun or an LMG, you do not have to craft a new weapon but only a module which costs far less resources to make. Switching between variations is done at the Graydale crafting table and takes very little time, so you can even switch mid firefight if really needed. The weapons are also generally cheaper than even vanilla weapons to manufacture and tend to posses good accuracy at the distances they're built to operate at.

All Panther MRS variants preform close to the same but will acomplish their purpose well enough to be worth it. The Panther-S LMG is probably the most reliable LMG in the game in terms of accuracy, Panther-R and Panther-C perform about the same in terms of damage but differ in optimal distance, Panther-M is essentially a faster firing, less damaging sniper rifle.

The Jaguar Multi-launcher is more accurate than a standard grenade launcher, though it posseses less damage per shot. One Jaguar can give your colony explosive, incindiery and smokescreen options for a low resources cost.

Comparing Graydale's close-range firearms, the Jaguar Buckshot setting does more instant burst damage than the other weapons but lacks in accuracy and fire-rate, the MRS Carbine and the Caracal HV SMG are just about the same in terms of close-range effectiveness in practice but the Carbine has greater range while the Caracal HV SMG has potentially more dps. In my own testing I've found that the Caracal is better suited for close-range combat compared to the above but only if you have the resources to spare and get one of the better quality modifiers when you craft it.

Grenades aren't much to mention as far as I can tell, they're essentially the same just less damaging but throwable more often.

The Combat Blade is a decent choice for melee, almost as good as a plasteel longsword and gives an increased plant-cutting speed so if you have a farmer who doesn't fight or if you have the Sidearm mod give one to them or your lumberjack for a little boost in workspeed.

Graydale's Laconian Pioneer Armor is basically normal Power Armor with several 10% bonuses to workspeed and effectiveness related to construction as well as a 10% bonus to aiming time. The armor is built for a "combat engineer" and does just as it says, any constructer or worker would benefit from this armor outside of combat as well. Since those bonuses do not increase or decrease with the quality or integrity of the Pioneer Armor, the Panther MRS or Multi-launcher become that much more reliable in conjuction with this power armor.



As for the Excelsior Melee Armor: if you are melee and not up against Federation units then use it. It gives not only several very good bonuses to melee-related stats but also a small personal shield that's essentially a shield belt without the belt. I have not yet fully tested what happens when a shield belt runs out while you are wearing this armor but based on what happens when you take one off while wearing it, it's likely that the armor's shields go inactive while a powered up shield belt is equipped. If the shield breaks then the armor's shield may activate and start regenerating immediately or the shield belt becomes your only shield source. In any case, a standard shield belt has more shield capacity than the armor's shield, whether it regenerates faster than the armor's or slower I haven't checked yet.


That's pretty much it for what I've found here.
In review:
- Yunhwa is specialized for unarmored targets and causing pain
- Jotun is specialized for killing mechanoids
- Tisiphone is purely blunt damage and annihilates Federation pawns but aren't more useful against anything else compared to the other options
- Graydale is the most reliable and adaptive set of arms, good for true Rimworld playthroughs
- Excelsior Armor = Melee's best friend
- be VERY afraid of Satchel Charge armed sappers, one will destroy your defenses in
seconds, two will obliterate them if they are not taken out first

(I seriously cannot stress this enough, the Satchel Charge does 200 damage a pop, turrets have a base 100hp, steel walls have 350hp, sandbags have 450hp. The reload time on SCs is less than 5 seconds; if you don't take out a sapper armed with them before they get to their target, they'll do some serious damage if not just destroy your walls and defenses and good luck if you have a pawn in the blast radious. If you're facing more than three... then you are boned and the AI storytellar either hates you or will fail to realize just how bad they've screwed you over.)



{as extra if you have other Rimsenal mods}

- Federation arms are good against the majority of targets and are best used at a distance,
their main drawbacks are low rof and very pricy to buy or resource heavy to make, all of
them use heat energy as their damage type

- Rimsenal Defense
- The Graydale HMG and HGL nests are amazing manned defense systems that easily
outshine mortars.
- The Jotun manned weapon systems are a bit bugged but easily destroy armored targets.
- Yunhwa automated turrets are best for pests, animal assaults and crowd control.
- Tisiphone's sniper turret is worthless at the moment, for some reason it has the turret's
accuracy listed at 35% if I recall, making the effective accuracy 29%. It rarely hits anything
and doesn't do enough damage to justify its combat implimenation even over a vanilla turret.
(This may have been fixed in the last update, have not yet checked.)

- EMP Rifle from Enhanced Vanilla is a beautifully OP thing, which is probably why a version of Enhanced Vanilla without the EMP Rifle was released. That and raiders with it will pretty much completely disable your defenses.



If you have any questions about these armaments let me know and please leave input on this if you've found anything else out too. If you find something that contradicts what I have here post that too, I'd love to know more about this stuff. I will be regularly updating this discussion with any new information I've found or corrections to any missinformation I've typed up here.

P.S. I have never used the Rimsenal Feral mod so I have no knowledge on what's best used against them but my guess is a mix of Yunhwa and Jotun weapons. I've used this mod along with Rimsenal Enhanced Vanilla, Federation and Defense, Sidearms, More Vanilla Turrets, Megafauna, Fences, Advanced Energy and ♥♥♥♥ Friendly Fire. I have not used it with that combat rebalancing mod I've heard of.

I realized that I have also never tested these weapons against mega-insects, nor do I have much experience fighting them since I usually do all I can to prevent an infestation. Considering the fact that they on paper have more resistance to sharp than blunt my best guess is that Tisiphone weapons would work better against them. If you have the Rimsenal Federation mod though then I assume that Federation weapons would be best since the mega-insects don't have any heat resistence (at least on the wiki). Any Input on that would be much oblidged.
