S "Best" Tier
"The Jock" Trent - With his low stamina consumption, he can easily distract or avoid the Slasher if you don't take it for granted.
"The Nerd" Noah - Can detect the Slasher and Teammates with his Tracker, the downside being it can't differentiate the two. But this shouldn't ever be an issue if you play smart.

A "Good" Tier
"The Popular Girl" Lynda - Knowing where the Police are is a very powerful tool, but it's situational and only comes into effect in the end-game. It's good to always stay near a Lynda.
"The Skeptical Cop" Gale - The Revolver is great for ending a chase or helping others, but the Revolver has very low stun duration and limited ammo.

B "Okay" Tier
"The Basketball Player" Rolland - Keys are okay, they don't neccessarily protect you forever and you only have 3 on you, but they can delay a chase or stop a Slasher in their tracks.
"The Finalist" Sydney - Being immune to the Slasher's is somewhat helpful and that's it.

C "Bad" Tier
"The Emo" Audrey - Her ability to be immune to fear, lacking a heartbeat, isn't actually that useful when the Slasher has to be literally touching you to hear it. This makes her basically useless.
"The Junky" Marty - Again, he's useless. His improved night vision barely does anything, I've found myself still having to use a flashlight to see things.
"The Fat Guy" Franklin - The worst character in the game, he is the strongest and has the most health, but his debuff is the worst. He consumes stamina faster, whilst it doesn't sound too bad, it really is. If you are in a group that's found, you will blow out first and be the first to die in the group, chases will end quickly for you. The high health compensates for nothing when you will inevitibly die if you are found.
