There's no way to tell overall. You have to go by modes.
Whether it's 1 vs 1 or 2 vs 2 is going to make a difference.
For instance, the general consensus right now is Kat might be top tier in 1 vs 1 but she's not nearly as good in 2 vs 2 as she relies on lengthy and specific setups that can easily be interrupted in a more chaotic enviroment.
Personal preference: Sweet Tooth Character that can destroy games and easy wins: Kratos
I like characters with more thought to them and yes Sweet Tooth has a simple moveset but I'm biased as I love Twisted Metal. Really enjoying Emmett at the moment also. Just need to work out his level 3 a bit more.
Stupid post. Do you not see the bottom option if you want to pick Jak?
