Wilder by KO. Louis' secret was his longevity. His resume and h2h ability were mediocre. Big dosser is "much" bigger man. He would decapitate Louis sadly.
Yes he lacks the ATG wins against Stiverne, Arreola and Luis Ortiz, only having wins over the likes of Baer, Schmeling and Walcott.
Louis fought some big guys back then who were actually close to a Wilders size. But they didn’t have mobility or power like Wilder. I’d go with Wilder, too big for Joe.
Being dropped by Jim Braddock isn’t as bad as getting dropped by Harold scornier to the point where he had to cheat lolol
Chisora would be sparked clean out. He's a pudding. Wilder may be a one trick pony, but he's tough as hell and would scare the living daylights out of the pretender that is Chisora.
