Theres some great names there as well as a few not mentioned. I honestly couldnt say who was better as they were all brilliant
Corro was a very good...even excellent defensive fighter..he was called by Victor Galindez the "Jimmy Young of Argentina", because he wasn't to thrilled with how Hugo won the title from Rodrigo valdez.
Canto wasn't too shabby either. He use to glide along the floor not wasting an ounce of energy. Very economical with his defense, which he had to be with all those distance fights, just brillient to watch.
