Tapia. He's like a technically superior Carlos Cuadras, and also much more talented. Rungvisai gets out-pointed soundly IMO.
I'll pick Tapia to win on a 7-5 or 8-4 points in a highly entertaining fight. Tapia would outbox SSR, and even when he gets caught up in an exchange I see Tapia getting the better of it due to his speed.
Mostly his personality. He was a true phony. Fought dirty all the time, and then pretended to be humble and religious afterwards. He was truly full of ****. And his annoying showboating was second only to Hamed. As for his style... didn't care for that either. But, I admit it was often effective.
