I watch both boxing and MMA buddy...
Record:
Tyson Fury: Vladamir Klitchko, Derek Chisora, Deontay Wilder
Anthony Joshua: Dillian Whyte, Vladamir Kitchko, Joseph Parker, Andy Ruiz, Kubrat Pulev, Alexander Povetkin, Carlos Takam
Belts:
Tyson Fury: WBC
Anthony Joshua: WBA, IBF, WBO, IBO
But Tyson Fury is the best HW? Lol, nobody that knows boxing and is objective would pick Fury over AJ. AJ's record is WAY better and he has more belts.
Anyway, I'm not saying I'd favor Ngannou to beat Fury. I'm only saying that he would have a chance, which I explained.
