Joshua, but wilder has great power as well when leveraged. I think there is a huge gap in their power when both are on the move as wilder is just hasn't learned to leverage power without being set.
Wilder seems to have to throw his entire body behind the right to be one-punch devastating. Joshua seems naturally heavy handed and generates huge power from the ground up.
Joshua knocks Molina, Szpilka out in the first round. Wilder power is terribly overrated. He couldn't hurt Stiverne, and Stiverne has been knocked down by feather fisted Derick Rossy. Plus Deontays chin is made of the finest glass on the market :good
We don't know anything about Joshuas chin, but I do know Wilder has the better resume so far. And to think Joshua KO's all those opponents is just wishful thinking imo.
Szpilka had to dive head first into Wilder's fist for him to knock him out. So, yeah his power is overrated.
