Vargas is way stronger, and accurate than Santos, and even though I had Santos losing he did rock Margarito and put up a good fight. Vargas is was to skilled, couples with his power to not beat Margarito. But I can see Tony checking Vargas'chin, son't take me wrong. I lean more towards Vargas based on overall talents.
You can measure this one by how long somebody has a been a fan. They think the guy they saw struggle with Mayorga and get blasted out by Mosley was Vargas.. Nah, THAT WAS A DIFFERENT PERSON.
