I'll go with Leonard, Hearns and Benitez. I'm not saying that they would be unbeaten in a series of fights with thier 90's counterparts but they would come out with more wins. Leonard has the edge in speed and mobility over everyone as well as underrated power. Benitez(a well trained Benitez) is as slick as they come and hard to hit cleanly and Hearns has the physical advantages as well as freakish power and underrated boxing ability. Great matchups though. It would be fun to watch these fighters get it on.
