IMHO, Usyk vs Fury 2 and Bivol vs Beterbiev 2 were -even- better performances than Bud's

Pretty much this.

As I think they fought even tougher opposition:
Fury's sheer size difference and Biev's ability to march you down with his insane power even hitting gloves (as happened in the 1st).

Even Usyk - Dubois 2 has a case, though it seems now DD is a can because Usyk did easy work.
Remember what he did to AJ.
