Becerra was a better technician and a big puncher in his own right, but im not too sure his chin is holding up to Zamora's power. I think its basically 50-50, but if forced to choose I'm more siding with Zamora.
I tend to agree, but Becerra's chin seemed to be very good. He did spend 30 rounds pressuring Medel without being KOed. Medel was young, but he was still KOing guys around their three fights. Just something to note, I think his chin was on a similar level to Zamora's. That said, I favour Zamora's superior firepower to win here if I was forced to choose. I think these two are on a similar level.
