i think you mean more skilled cause neither is the most skilled sadly my Duran knowledge is not as good as it should be but id be willing to say he is a better boxer going by his close but clear win over Leonard as a prime example the guy was a wizard in the ring Floyds great too, this is a tough call cause both men are different styles but experts in their own way i will say i dont know any examples of Duran neutralizing and dominating guys in the way Floyd has
Chin,Stamina,Defense,Counter-Punching,Foot-movement, Punch-Selection,Timing. What else you got? You name it, Mayweather has the advantage excluding power.
