Mayweather is the better boxer. But, because he's just a welterweight, and not a very big one, Vitali would probably kill Mayweather, literally, if he landed a good punch.

You should seek the permission of at least ten contributors before asking questions again. I doubt many would take this question seriously.
Floyd is obviously the better boxer, but due to size and strength differential, Vitali would knock him out with a jab.
Vitali is both the better boxer and would destroy Mayweather inside a round. Mayweather is a coward who ducked the best available fighters during his career, got at last 3 gift decisions and his 0 is fake....How the heck he's better than Vitali? Vitali is a legend, Mayweather is a ducker and coward. You do the math.
How about read more about weight-classes? Mayweather is in different weight division...he is simply way lighter and any Top 10 HW will destroy him. Pulev, Povetkin, Fury, Helenius, Dimitrenko etc - they'd do it.
Having said that I like Mayweather, good stylle, pretty good boxer overall.
