Chisora is good, he's a better win than nearly all of Wilder's opponents, the only arguable 1 is Ortiz. He only got knocked out clean once that I remember and ironically that was against Dillian Whyte in the 2nd fight, with Haye the ref stopped it and with Fury the 2nd fight his corner stopped it. Chisora for sure has fought higher level opponents than Wilder also, fought Vitali, Haye, Fury, Whyte, 3 of them which Wilder avoided, the other 1 he cherrypicked and just got battered by so it's hard to gage. He beat Takam, Price, and a bunch of opponents Wilder beat, sometimes in better fashion, he knocked Szpilka out way quicker than Wilder did, knocked out Malik Scott too, a few of his decisions vs him were very controversial too. I think you said previously yourself that you thought he won the first fight vs Dillian Whyte, if that's the case he should have a better win on his record than Wilder does in his whole career then. He's proven he can at least compete at top level, even if he may not be the very elite, he's the level just below, B level, most of Wilder's opponents are way lower than that, Ortiz may be B level too but extremely unproven.
