It's gotta be Floyd, surely? Marciano has some big names (Moore, Walcott and Charles) but he wasn't particularly skilled and he didn't fight any great fighter in his prime. Having said that, winning the heavyweight title was a huge deal back then and historically that helps him.
Still, for my money, it's Mayweather.

Hearns would have knocked Floyd's brains into the 3rd row, Whitaker would have made him look like he was chuvalo, and Floyd blatantly ducked Margarito and Williams, you're obviously a Floyd worshipping fanboy.
