I believe that they are both up there but to pick one.........wow!
i think it's impossible both fights had there caliber and just two different styles on how they approached each other.
Now knowing that if Castillo would have made weight for the second and third then maybe it would have been different but i believe that from the trilogy between Vasquez and Marquez and those three aginast just one outstanding match is undebateable.

I'll leave the rest for you to decide.............PEACE!!!!!!!
