Your Favorite Mexico vs Puerto Rico fights.?

I want to say it was Margarito-Cotto...what an epic battle of 2 forward fighting bulls. You had the WBO and WBo title on line. Cotto losing his 0 by late KO...then the controversy afterward. His children and wife crying as his corner throws in th towel as he is bloodied and beaten, although he showed himself to be a boxer not just a brawler.
