I recently did a playthrough of the entire game with these mods as the main gameplay-altering mods, with really only quality of life mods besides them. Here are my thoughts on the various mods:
Speed Buffs: This is the mod I've used for the longest, even before this playthrough. I like it a lot, as it make a lot of keypages more useful in all stages of the game. It even makes some fights a little bit harder when the enemies can get extra speed dice, especially the index proselytes and church of gears worshipers. One thing is I feel that post-haste should cost 3 for attribution, as theres not much of a reason not to use it for a lot of decks with how cheap it is currently. I also didn't get to see the impact of the early post-haste since that was added after I had reached much further in my playthrough.

Less Tired Yujin: I turned off the namesake change of the mod, removing Yujin's broken speed die, as I mainly used this mod for the changes to Valentin's and Tenma's Kizuna, to better use the changed Shi pages in the card tweaks mod.

Patron Extras: Malkuth breathing is hilariously overpowered, although thats the point. I liked the new passives for the Black Silence and the Red Mist, especially in encouraging a non-solo setup on Gebura's floor.

Extra Cards: Off with their Head is cool, especially as a nice single-use card to thin decks, especially with Field Mods being changed in another mod. I didn't really use the other cards that much, and I think some of the Crying Children pages are a little weak, although the 4 dice might make them better than I think.

8 o'clock Circus Buffs: I didn't really use the changed ranged pages, but Quickdraw was nice for attribution.

Carnival Buffs: I enjoyed more/earlier access to skim prescript. I already liked Will Make Fine Silk for hand-filling decks, and the extra card draw on it helps with that. The other pages are nice, but they do get outclassed pretty quickly (although thats just how that section of the game goes).

Purple Tear Buffs: Serpent Sword Technique is nice for making slash focused bleed decks instead of pierce focused ones. I also enjoyed having some actually good blunt cards in Star of the City. The Mirage Storm change is fun, although its still a little hard to use. I think the counter die on Violet Blade is maybe a bit too strong; I don't think any offensive counter dice in vanilla go above 4-8 besides EGO and hard to use stuff.

Hana Association Buffs: Forward march is nice as a general light gain card for longer battles. Godspeed is fun on Mirinae, Myo, and the changed Harold. Unyielding Strike is finally a good Creak sidegrade! Divinatory Impact is funny, although I did keep the old dice order. With the new dice order it is better in defensive decks though. I especially like that Harold actually has a niche now instead of being a weaker Olivier.

Index Tweaks: Undertake Prescript is a good creak sidegrade and provides more draw options. Proselyte's Blade was nice against Burrowing Heaven, and it was already a good option in power-null situations so it's cool that it can be useful in more fights now. Eliminate is is really funny, and is useful even without the on-kill or low health effects-maybe a bit too good? Unlock is also maybe a bit too good, it was already one of the better card draw options since it was light positive at Unlock III, and making it card positive for I and II makes it really strong. I liked using Distorted Yan with the changes to two of his exclusive pages, and even with saddling him with clone and distorted blade for if it reaches EL 5 he still had good clashing potential. Sword of Volition is fun with Ominous Power shenanigans, and it is really good in the Pluto fight with the light contract. Blind Faith is just good to use in general, although also maybe a touch too strong (good clashing, card draw, and cost reduction).

Liu Buffs: Fleet Edge is fun on Myo or in general. High Kick is nice on Singular Strike decks to help against 2 die pages, and hard counters some nasty pages like the Liu exclusives or Lock. Bi An is maybe a bit too strong, since it was already a really good page and didn't really need +2 to min and max. Singular Strike Xiao with Jin Ni was my favorite new deck in the entire run even with only getting it at basically the end of Star of the City. I really like the changes to all of the passives that trigger on emotion level up now also working when at max emotion level. The other page changes were nice too, especially Flow of the Sword.

R-Corp Buffs: Battle Command and Quick Suppression for full charge teams (and the latter was nice on an evade-focused Myo). Concentration is helpful for cycling through charge decks. The Alt-Grunt Passives are cool, especially Rhino Treatment on a block focused Yujin. I was not a fan of the R-Mod passives, since they made it hard to keep enough charge for the economy cards and the other charge spending cards, although you did make it an option so in the future I would disable it.

WARP Crew Buffs: Sen and Lesti's changed passives are cool to attribute on charge decks (or even decks in general) for extra damage plus the lasting boosts to offensive and defensive dice. Rose was fun to use, especially with the Speed Buff mod.

General Reception Buffs: Jikan was just a bit nicer in general. The buffed pierce pages were cool, especially Refine being all pierce dice. Jeong's office has a ton of cool buffs, especially with Sakura actually being useful, and LaNHaD being a fun design that I've used in other mods too. I didn't really use Seven Association, the Night Awls, or Leaflet Workshop stuff much, the latter two because I've used them in playthroughs before and they weren't changed too much, and especially not the smoke stuff because I'm not a big fan of smoke. Decisive Dive is my favorite new passive (not including Post-Haste), and its nice on non-Singular Strike decks too, especially cards with a block die followed by a slash die. Striker's Stance is funny too. The better bleed pages were really handy against Greta, and I built up a ton of bleed on her even without getting the double bleed abno page. The Udjat stuff is really cool, although I didn't use it too much as I used the Udjat more for Nix/Mountain of Corpses shenanigans rather than actually building them to win themselves. I loved the additional discard support in Mirae Life Insurance, especially with them having a useful passive for it now. Back to Leaflet, new Field Mods is cool in its new niche, but I missed the old one, even with Off with their Heads kinda filling its spot. The Bayard Office changes were really cool, especially the self-status ailment support, and Great Swing is nice as a panic button or on Purple Tear or Bayard.

Card Tweaks: There were a lot of little changes here, so I'll go over the ones that impacted me a lot. Hand-fill Yujin was already a deck I liked to use, so Ink Over now drawing a card made it even better. Collision was nice to get a bit more light back in pierce decks. Fierce Charge was a nice option on Valentin. All of the Shi page changes were cool/useful in various decks. Manikin was a nice option in more defensive decks to be able to clash easier. Summary Judgement and Suppressing Shot are massive changes for ammo focused decks. Ferrous Guard was like Manikin. Energy Conversion is maybe a bit too good now, +3 light is a lot for only 4 charge, and it can still draw. Absorb Impact was a nice change to make it distinct from Bulky Impact, but it was a little hard to use later in the fight since you often want to gain charge after spending it.

Passive Tweaks: Again I'm only going over the changes that impacted my playthough a lot, and this only came out after I had reached Star of the City so I didn't get the full impact of the early changes. I'm not a big fan of the Electric Shock change, since it was a nice space-filler at 1 cost, and fairy reliable to trigger anyways. Axe Gang Spirit is maybe a bit too good as is, with a 1/3 chance of a fair amount of paralysis, and the bleed or fragile aren't bad either. I like the repeating effects on the various act start passives (like Meow Meow). The Deflect Assault change really helps make defensive Yujin strong (along with stuff previously mentioned). Minimum Offense was a really nice passive in general, especially on the Red Mist, the Black Silence, and Olivier with weight of sin. Tough it Out and Pete's passive are nice when going for Mountain of Corpses to have even more protection.

Overall, I really liked all these mods, and would recommend them to anyone doing a fresh playthrough!
