I actually disagree...pbf was more dominant because his power was more dangerous at 130 and 135. At welterweight his defense became more important and he knocked out less boxers...but also became literally the greatest defensive boxer of all time.That's a very good choice too. But a lot of people are confused about Floyd's actual Prime
IMO he started his prime when he became Pretty Boy Floyd and was physically at his best. When he became Money Mayweather he was still in his prime but not at the level he was at when he was PBF imo
It's like the opposite of Barry bonds and his weight...both halves of his career are GOAT status
I don't think he was ever out of his prime.
