Gotta say mine will always be DIO. He's just so fun and satisfying to screw around with, and his voice is just top notch. I also really like the edits they have. Best one I know of, called ****** DIO (It's not what it sounds like, swear on my life) gives him pretty much all his move sets from every playable version of himself, plus a few extra from the anime like his street sign axe and his "SHINE KAKYOIN" attack.
