Who do you think hits harder between the two? I say Kovalev because he's bigger and I feel he's fought better opponents.
Kovalev has more raw power, GG generates his from a combination of natural power, perfect balance and technique
Kovalev's a 175lb engine of aggression...Golovkin is very heavy handed but a more cautiously aggressive MW. I kinda have to go with Kovalev, but P4P who knows? Really like both fighters and both carry considerable power (though I always will contend that KOs come more from accuracy and timing than 'power') I think Kovalev is the guy that will continue to get the most big KOs, but also the guy that'll lose first.
golovkin ran kovalev out of big bear. they had the same trainer...but rumor has it ggg was whoopin that ass in sparring so kovalev left.
kovalev looks like everything he throws hurts.... he stopped a mutha****a with a jab.... doesn't get much harder than that.
