I'd favor Berbick as well. Better chin, somewhat more consistent, fought at an advanced age with far more success then Maskaev.
Berbick by KO. I was ringside when Oliver McCall mopped the floor with Maskaev. Berbick was better than McCall.
I just don't see a reason to favour Maskaev. But there is a reason why they called him "The Big O." And that reason is because he could sing exactly like Roy Orbison. So, that might help him out at some point during the fight.
