Their first fight in 2019 was arguably the best matchup of the year. The rematch will arguably be the best matchup this year. Both guys are young, in their physical primes still, and besides Anderson Silva, they are arguably the best to ever do it at 185. Both undefeated at 185 outside of their match. For middleweight I'd say the closest duo might have been Weidman/Rockhold but they both proceeded to continuously get KTFO after their match. What about other divisions? At 205 I'd say Jones/DC. Maybe Aldo/Mendes at 145???
