Perez for me,he is top 3 at the weight,Villa beat an old faded champ,against a prime Perez ,I see only one winner ,and it isnt Pancho.
Villa is one of the greatest Flys ever, and looks good on the limited footage we have of him. Cross guard, great positioning, good ring IQ and he looks very strong and durable It's not that Perez isn't great; Pancho was just greater. So I side with him. Perez is very strong H2H, but he could get Sloppy and wild, and pacho could tag him with those sharp uppercuts and stay inside IMO. However, I could see him wining a 12 rounder maybe.
