Lewis v Vitali was the best fight. How Vitali's head remained intact from that uppercut is a mystery.
Usyk vs Fury definitely for me. Vitali was HUGE underdog against Lewis, 5 to 1 underdog. Wlad was a big favourite vs Fury. Wlad vs Haye was considered far more even and intriguing fight than either Lewis vs Vitali or Wlad vs Fury, although it happened to be uncompetitive while Lewis and Vitali turned out to be far better and more competitive than expected. Usyk vs Fury was not only considered 50/50 fight before they met in the ring, but also fight itself exceeded all expectations in terms of drama and action.
But if you mean purely action inside the ring then you should definitely take some fights from the poll and replace them with Vitali vs Sanders, Liamhovoch vs Brewster and Whyte vs Chisora I fights
I guess it depends on how much you value quality and elite boxing in the discussion, or just look for drama and guts. Usyk vs Fury or Usyk v Joshua 2 would get my vote in terms of overall quality, with Usyk v Fury edging it due to that awesome round 9. Wow. Although the quality of the boxing was significantly lower, any of the Fury v Wilder fights score high in terms of drama, heart and action. It's really hard to beat that 12th round KD and miraculous recovery in the 1st for drama. AJ v Wlad was a great encounter as well, with Wlad showing MUCh more than he showed against Fury, and Joshua showing fortitude to come back from that heavy right hand from Dr Steelhammer. Someone mentioned Liakhovic vs Brewster - and regardless of it being a title fight, that probably gets the nod for action - it is really hard to top what those guys put into that fight - and what it probably took out of them! Titanic scrap!
Man I feel like I'm going down memory lane now Chisora-Whyte 1 was epic edge of the seat stuff for twelve rounds.
The best fight was Aj v wlad, followed By the Fury v Wilder 1 and 3 fights for entertainment Chisora vs whyte 1 was a cracker I also loved Seeing Ruiz cream Aj
