Probably Lewis. Both have huge ring IQ's and are great at adapting, but one of them is a power punching super heavyweight who was excellent at turning a chess match into a brawl when needed.
Lewis wins by UD. Uysk is so smart he won't get stopped but Lewis could jab his head off, uppercut and hold. Lewis H2H is top 3.
Wait for Usyk to fight a real heavyweight Not Chisora or AJ. AJ is a total bum but people don't understand it yet. Usyk was wise try and make sure he is 100% for Fury with his little holiday.
It's so sad that people still doubt Usyk and only his win vs Fury would change some of the boxing fans minds.
lewis by ud or late stoppage, just like usyk,lewis has great ring iq,but lewis is much more powerful and heavier and would slowly pummel usyk,would be a fun fight to watch
Lewis gets taken to slick school. Usyk is too fast and took slick for him. I see zero slickness on his CV. That moribund Croatian butcher who was Usyk sized would've beat him had he not abandoned his movement and opted to fight Lewis' fight.
Lewis dined on big slow stiffs and plodders and everyone knows the antidote to big powerful giants is fast, slick boxer movers. We've seen Usyk slay many big powerful behemoths but we've never seen Lewis slay a slickster. Also Lewis' record against the Soviet school isn't great. Not saying Lewis wasn't a great HW but it's a different ballgame when you get in there with an elusive slickster who is fleeter of hand and foot than you and who isn't there for you to land your bombs on. Also we'd stick a prime Usyk in there not this aged one.
AJ is not a bum. He stopped Wlad, while Fury squeaked past him. Fury's resume is still unremarkable, AJ's is better. I suspect Lewis wins against Usyk. He is clearly better than this reign of HWs including Fury, AJ. His size advantage over Usyk should be enough for a win.
