Let's say all these fighters square off at a 147 lbs catchweight, and fight each other fighter in their own division (A or B) in a round robin. Then the first place of division A faces the 2nd place of division B. The winner of division B faces the 2nd place of division A. The two winners square off in the final. Division A: Donald Curry Wilfredo Benitez Aaron Pryor Oscar Dela Hoya Division B: Floyd Mayweather Jr. Felix Trinidad Pernell Whitaker Shane Mosley Have fun !
I think Don Curry at his best takes Division A, his toughest comp would have been Benitez. Aaron Pryor would make his presence felt but is too small at 140 lbs. Mayweather takes Division B. His footwork gets him by Trinidad, his toughest fight would be a welterweight Whitaker from a stylistic point. But Mayweather takes a decision with overall accuracy and jab. Overall winner: Mayweather. Footwork and defense keeps him out of exchanges with a dangerous welterweight, and overall speed gives him a decision win.
