I voted Pacquiao simply because Floyd fought a Cotto who took a beating from Manny and also had more mileage from other fights. The truth is, Cotto can be hit and against Pacquiao that is not a good trait. Cotto was probably not far apart in both fights, it's just Manny has a bit more power than Floyd thus he busted him up a bit more. You could argue that Cotto was more comfortable at 154lbs or the 10oz gloves negated some of Floyd's power but looking at their records and fights, it's more likely Pacquiao does indeed have a little more dynamite in those hands and that was the difference.
