Hmm,this is also a way to see, who's the better fighter st 130 too? Chacon may had more power than Barrera at 130,but he has more CTE with his play style not really changing much except him being a bit more technical than the young,high paced version of him. Barrera also got more technical,but I believe he had better counterpunching abilities than Chacon and didn't really left his chin wide open like the schoolboy did.
Chacon by Unanimous decision probably, Barrera is not a Super Featherweight he was at his prime at the end of his last fight at 115 lbs and specially his period of prime was at 122 lbs (Super Bantamweight).
