It could be argued that Kamali has placed better at times but none of us really believe that King was in Prince's league. The better question really would be Prince or Francois. In which case I'd say Francois.
QFT...francois had a lot better upper body and legs to match...prince, to be brutally honest, was only hams and tris...maybe delts...mike also had that solid, granite-like look, guys nowadays seem to lack...maybe he truly had a foundation, who knows
continuing being brutally honest neither of those guys truly had flow in there physiques...prince maybe had a better structure but he kinda messed up with it in his later years...francois was able to keep his waist tight etc but he just was born with that blocky look...nowhere near as bad as current mr o though...
