Out of the ones you have listed, I would say Vlad vs Joshua or Vital vs Lewis. Brewster vs Lehovich was good. I'm sure I butchered his name.
Only just falls within the last twenty years, but anyone who hasn't yet seen Clifford Etienne's war against Lawrence Clay Bey should really check it out. What a fight.
danny williams v mark potter danny dislocates his right shoulder twice and still manages to knock potter out in the sixth with only one working arm. bonkers.
Joshua-Klitshcko Lewis-Klitshcko Whyte-Chisora I Have probably been the best. My favorite was seeing that POS fraud Wilder get his ass handed to him in February by Fury and come out with the funniest excuses ever told.
