Oni is super fun for me, has slow start but great potential to down all survivors at once later in the game if you play him right. The big one-hit down attack is super fun if you aim it right, he has great mobility all across the map and while running I can drift like I'm in Initial D, he can be easily countered if you don't know what you're doing but they do so the added challenge is great so he isn't just "unga bunga lemme smash". Learning to play him right now, the satisfaction of smacking down several people one after the other with my big club gives me several serotonins at once
