Valdez. Far more refined and polished. Murderous puncher. More durable (Difference between durability and guts/grit)
Valdez could sometimes be lazy with his jab and allow a fighter like Antuofermo to get in on him (see his fights with Briscoe). He also tended to fight in spurts and flurries, whereas Antuofermo tended to keep throwing non-stop. Still, I think Valdez's quicker, sharper, and harder punching gives him a points-edge throughout, and there's the possibility that he might even stop Antuofermo. Either way, it's a slugfest.
Valdez is an underated middle ,whilst Vito is fairly ordinary Valdez beats him up.A stoppage due to facial damage inside 8 rds.
