Pac by a million miles , pac is properly world famous , outside of the US and PR I don't think Cotto is a huge name.
I remember even when Pac fought Solis the bar was full of people. When Cotto fought Gomez it was pretty empty. When Cotto fought Margarito it was full tho, but when Pac fought JMM you couldn't even get a seat. I think that at this point Pac is known to sports fans around the world, not just boxing fans. And no, I'm not trying to nuthug. I'm just saying what I think it is.
Pac by a mile. Considering his upbrining, his fan base loyalty, his "for the people" mentatlity... His wins over all-time greats. His wins in different weight classes... Plus how many mainstream Pinoys become world champs at his level??
