For pure power (take away delivery etc) I'd go Smith Jr Beterbiev Stevenson Kovalev Add in timing and coordination etc that is necessary to hit the moving target effectively I'd go Beterbiev Stevenson Kovalev Smith Jr If I had to stand still and take a belt from one of them , I'd have to take Kov If I was allowed to get my running shoes on, give me Smith Jr
I wouldn't be in a mad rush to get chinned off any of them to be honest... Kovalev doesn't seem to pack any of the dynamite he used to have..but there's no doubting he was a puncher I'd say for pure one hit night night boboes power was probably Stevenson..the power plus the speed Beterbiev Seems to have that GGG type power..where everything hurts ...I'd probably rather take one clean to the chin off Stevenson than the sustained pummeling from beterbiev Joe Smith's definitely a banger hard to tell if he's outright the biggest puncher though as he's a bit easier to read and lacks a few of the skills the others had in regards to landing the perfect shot...not trying to do Joe a disservice with this comment as I like him I just think the others had better delivery of their shots n disguise them better
