Shoshana, with that name you are meant to be a good Orthodox Jewish virgin girl! .............. Statistically he's the biggest puncher to cross over in the last 25 years (at least).
If you base it off of their one shared opponent Campillo, then no. Kovalev got him out in 3 (a younger fresher version), it took Beterbiev 4.
Yes, Gassiev does infact hit harder than Kovalev. He has a 100 % ko rate and has been fighting legit guys. Campillo and Cloud where former World Champions and World Class level. He was already fighting them with less than 10 fights.
You know better than that! You are just bias here. Kovalev may have more power than Betterbiev (I think Kovalev on a bag will produce more power, his punches have some whip in them). I think though Beterbiev hits harder any other way. But it doesn't mean because one guy finishes some common opponent before the other that it will always be the case with every opponent. Plus you prefere Kovalev over Betterbiev.
One of the Beterbiev-Kovalev matches in the ams was 25-24 for Beterbiev, so its best to not read too much into it, that's pretty friggin evenly matched.
I'm biased? Says the guy who defends every Canadian fighter on the planet, even the ones who weren't born there and recently emigrated. Their power is pretty even, I doubt we'd see a different outcome if that was Kovalev in there with Prieto tonight, it might have lasted 2 since Kovalev usually tries to feel guys out for a round first.
We won't know who hits harder unless they both take their best shots at a pressure guage that can measure impact force.
