IMO...

1. Pacman
2. Winky
3. PBF

PBF is the more naturally talented of the group but he really hasnt fought anybody to truly prove how much talent he has. He hasnt had a gut check fight since Castillo 2. It seems like Pacman and Winky are in gut check fights every other fight. I think they are all close, but put Pacman and Winky ahead because they have proved how good they are against tougher competition.
