Power-wise, Berrio's starching of Stieglitz was more impressive than anything Miranda has done in his career. Until Miranda gets a KO victory even close to impressive as that, I will continue believing that Berrio is a clearly bigger puncher. Maybe I shouldn't have said "MUCH MORE", but it's a significant amount more IMO.
Additionally, Berrio has a 96% KO rate (all at SMW) compared to 87% for Miranda (and predominantly at MW).
Berrio's all early fights were at 160lbs or under. Yes, he has the 'better' KOs at SMW. But Miranda hasnt fought anyone decent at SMW yet. But at 160lbs, they fought the same opponents and Miranda had the better KO wins. As a matter of fact, out of ALL of Miranda wins, I cant think of anyone he fought that another fighter has KO'd earlier (except for Davis that was stopped one round earlier then Miranda did) You surely cant say that for Berrios.
Stupid, childish, but still pretty damn funny! Kinda like when the ketchup makes a fart sound. Makes you laugh whether you are 5 or 55!
On the other hand, Miranda has the more proven chin (although his is spectacular by no means), and is significantly quicker than Berrio, when he's motivated. Berrio's the more active guy generally though, and honestly has better killer instinct than Miranda (who always seems to have a few seconds lag between when he has a guy hurt and when he figures out that the other guy is hurt). I'd lean Miranda, primarily because of the handspeed, but I could also see Berrio KOing Miranda relatively early if Miranda comes out cautious like he's been doing lately. I voted for the last option. The under would be one of the safest bets out there for this one.
