The verdict
Dead even across the measured categories. Our all-time ranking places Jon Jones at #1 and José Aldo at #8.
The case for Jon Jones
Widely regarded as the most complete fighter the sport has produced, Jones holds a record of 28-1 with the lone loss a controversial 2009 disqualification for illegal downward elbows against Matt Hamill — a fight he was dominating. He became the youngest UFC champion in history at 23 by stopping Shogun Rua at UFC 128 in 2011, then ruled light heavyweight for nearly a decade, beating Daniel Cormier, Alexander Gustafsson, Lyoto Machida, Vitor Belfort, Glover Teixeira, Thiago Santos and Dominick Reyes. In 2023 he moved up to heavyweight and submitted Ciryl Gane for the vacant title at UFC 285, then stopped former champion Stipe Miocic with a spinning back kick to the body at UFC 309 in 2024. His unmatched reach, creativity and fight IQ are shadowed only by suspensions and legal issues outside the cage.
The case for José Aldo
The greatest featherweight of all time, Aldo went undefeated for roughly a decade — an 18-fight win streak from 2005 to 2015 — while reigning as WEC and then inaugural UFC featherweight champion. His leg kicks were the most feared in the sport, memorably crumpling Urijah Faber and reducing opponents to hobbling targets, and he paired them with sharp boxing and elite takedown defense. He defended the featherweight crown repeatedly against the division's best before Conor McGregor stunned him with a 13-second knockout at UFC 194 in 2015, one of the most shocking moments in MMA history. He rebuilt himself as a top bantamweight contender in his thirties, challenging for that title too, and retired from MMA around 31-8. For pure divisional dominance over a sustained period, few careers rival his prime.
