1. Demetrious Johnson: Good boxing, kicks, clinch knees/elbows, takedowns and top control, submission offense, elite scrambling ability and defensive grappling, decent TDD.
2. GSP: Good striking at range, vulnerable in the pocket/clinch, GOAT takedowns + top control + GNP, strong submission game and elite TDD.
3. Islam: Good counter-striking, very good wrestling takedowns + trips in the clinch, top control and submissions are elite, very hard to take down.
4. Volk: Elite striking, solid wrestling takedowns and trips, little sub offense but very good GNP, solid TDD and elite defensive grappling.
5. Jon Jones: Good kicks + knees + elbows, subpar boxing and dirty eyepoke defense, good takedowns/throws, elite ground and pound, strong submission game, nasty clinch striking, flawless TDD.
6. Petr Yan: All the tools on the feet, strong offensive wrestling + good GNP, minimal sub offense, TDD is solid but not flawless, same for defensive grappling (see Aljo fight).
7. Jose Aldo: Elite hands, head movement, footwork/pivots, kicks are nasty, GOAT TDD, defensive grappling can break down when tired, flawed clinch game in latter half of career.
8. Ilia Topuria: Elite boxing + accuracy, head movement is solid but not perfect, doesn't check much kicks but good at countering, strong clinch + throws, good ground game, TDD not proven enough.
9. Fedor: Good timing + accuracy with the hands, good kick defense, good at scrambling off his back, good takedown entries, clinch control is second to none.
10. Oliveira: Good offensive striking, very flawed defense, strong body lock takedowns, elite on the ground with subs, dangerous off his back but vulnerable to GNP sometimes, good clinch striking.
