I've been watching ALOT of both lately...these two are usually rated top 5 or top 10 of all time, who was greater?

I say Ali, HANDS DOWN. Only Ray Robinson is maybe greater than Ali to me.

Ali is greater...

But watch this vid....it's well worth it. You have to watch it all the way through.

There is no question. Ali transcended the sport and went beyond boxing.

Ali.

Not close.

Ray Leonard isn't in the top 10.

Ali is greater than Leonard.

this is not even a debate... lol.. ali was by far greater than leonard.. i would put leonard in the top 20 somewhere maybe...

Ali is simply greater. Everyday and twice on Sunday.

SRL was probably better p4p imo, if it matters at all to the discussion.

IMO, Ali is the GOAT of his division.

Not so with Leonard.

Ali hands down.

a good question is what fighter in his prime could have really competed with ray robinson in his prime?... welter to middle take your pick... i know most wont agree but i would love a mythical match up of robinson vs prime roy jones at middleweight or robinson vs. pernell whitaker at welterweight... whitaker was better at 135 but for weight to weight comparison id go with whitaker at welterweight.... those are the only 2 to me that come to mind...
