I have to say Barrera-Morrales... they are more skilled, they fought IMO with more fury, and they fought better. I think Marquez-Vazquez had that special edge that you get seeing Cotto fight in that both fighters carry that certain sense of vulnerability because they had been stopped in the past before, however Marquez isn't as good as his bro who is IMO on the same plane as Morrales and Barrera.
