Cotto over Quintana, easy. Norris beat a post-Chavez Meldrick Taylor who was only about 60% of pre-Chavez Taylor.
Odd comparison,Taylor was a much better fighter than Quintana but he was already past it by the time faced Norris while Quintana was undefeated when Cotto faced him and went on to beat Williams after getting destroyed by Cotto. I would say Cotto's win over Quintana even though i think that even the version of Taylor that lost to Norris would beat Quintana in a fight.
I agree with this 100%,especially the last sentence. Everybody here knows that Cotto and Norris are my two favorite fighters .
