I think we all knew this. Peak Mayweather edges out peak Pacquiao via UD. Pac will surely have his moments, as he did, but stylistically, you'd always bet on FMJ. The only person who didn't believe it, even during their fight that he's supposedly winning, was "why are you fighting scared" Floyd himself.
Floyd is probably better H2H than Pac. But then again andrzej fonfara KO Mayweather. So take the H2H thing for what its worth. The fact that Pac is even compared to Mayweather demonstrates hes the better p4p fighter. Max Kellerman has long pointed this out.
What's the debate? Who is the better fighter? I think its Mayweather. In my lifetime (was born in 92) Lennox Lewis is the best fighter. Mayweather doesnt crack the top 1000. If we are talking p4p well then it is Mayweather who is NOT in Pacquiaos league.
