The case for Georges St-Pierre
The most dominant welterweight in history and a paragon of preparation, GSP retired at 26-2 having avenged both losses. He first won the welterweight title from Matt Hughes at UFC 65 in 2006, suffered a stunning upset knockout by Matt Serra in 2007, then reclaimed the belt and never lost again, defending it nine consecutive times against a murderer's row that included B.J. Penn, Jon Fitch, Thiago Alves, Jake Shields and Nick Diaz. Famous for tailoring a specific game plan to every opponent — wrestling strikers and out-striking wrestlers — he combined an elite jab with suffocating top control. After a four-year hiatus he returned at UFC 217 in 2017 to submit middleweight champion Michael Bisping, becoming a two-division titleholder, then retired on top. His run of 13 title-fight wins stood as a record and his professionalism reshaped the sport.
The case for Stipe Miocic
The most accomplished heavyweight in UFC history, Miocic set the record for most consecutive successful heavyweight title defenses with three, a mark that stood alone in the sport's most volatile division. A working firefighter and paramedic, he won the title by knocking out Fabricio Werdum in Brazil at UFC 198 in 2016, then defended against Alistair Overeem, Junior dos Santos and Francis Ngannou. After dropping the belt to Daniel Cormier he reclaimed it in their 2019 rematch at UFC 241, avenging the loss. Built on crisp boxing, an underrated clinch and championship-round cardio, his reign gave heavyweight a rare stretch of stability. His career sits around 20-5, with the closing chapters — a knockout loss to Ngannou in 2021 and a stoppage by Jon Jones at UFC 309 in 2024 — coming against two of the hardest hitters the division has ever seen.
