I’ll take Wladimir, Wilder, and Big George.. Say what you will about level of opposition, the way people reacted and MELTED to Wilder’s power isn’t something you saw even with Wlad and George against lesser opp….
FOREMAN he had more fights than most everybody else on that list bar Shavers Chuvalo Williams who all had more losses anyway,he won World titles older than everybody else on that list,he fought in more eras than everybody else on that list . Some of those names on that list never even won a World Title .
I think this question is already answered by many boxing experts and afaik all agree that its something between the 88 version of mike tyson and the prime time deontay wilder.

1.Félix Savón (arguably the best HW in history, who even floored David Tua) 2.Deontay Wilder 3.George Foreman 4.Earnie Shavers 5.Anthony Joshua 6.the two Klitschko sisters 7.Lennox Lewis 8.Mike Tyson 9.Ike Ibeabuchi 10.Tommy Morrison 11.Paul Malignaggi
Freddie Roach said Wlad hit harder than Tyson. Steward said he hit harder than Lewis. He was also way bigger than Shavers was. It's not far fetched to think he punched harder than him. Also: https://www.boxingforum24.com/threads/wladimir’s-incredible-power.718532/
Sometimes it was blatantly faked, like when Liahkovich took they payoff and put on the worst acting job ever.
Some people said that because he had a higher stoppage rate. But Vitali even though he had power was largely a accumulation puncher and threw a lot more punches to get those stoppages.
I'm not convinced that fighter's are necassarily the best when it comes to judging an opponents power. They all have different definitions in their mind of what "power" is and punches can feel different, I'm sure a bunch of the guys who were KO'd by Wilder probably didn't even feel the punch that KO'd them for example. Look at Parker, he said Ruiz was the hardest puncher he ever faced, not the Zhang, Joshua, Wilder etc even though Zhang knocked him down.
I think truly big punchers have a ko percentage of 85% and above. Tyson, Bruno, Morrison all fulfill that criteria, as does Shannon Briggs. Joe Louis, Marciano both up there, Foreman is above 85%, but I think Wlad is higher than him, just...but Wilder is almost 95% from memory. That is terrifying power.
