I'd say his last two are the best.
The Teon Kennedy fight posted above, where he looks godly and the Marroquin fight.
People point to the two clean punches that landed on him in that fight as proof that he wouldn't hold up to the elite, but those are ridiculous standards. He never fell, took those punches and fought back, knocked down and bloodied up his much larger opponent. It's not the KO finish that you see with the Ramos fight, but a better performance to see his overall skills against a larger foe.
If you just want to see him blow someone out of the water, check out the Casey fight
