He doesn't have a better jab and I think Devon has quicker hands and feet
Keith got that one punch power though
Keith doesn't slap with his jab like Devon does from time to time and he doesn't do all that grunting shyt either.
Their speed and overall quickness is close enough to where it can go either way to be honest.
Alexander just has the experience and better chin.
Thurman showed us he can adjust during fights even if it's against limited comp, while Devon just fights harder
