Jon Jones is by far the best, most skilled, most naturally gifted UFC fighter I have ever seen compete in years of watching UFC and combat sports.
He's the Pound for Pound best fighter in the world when he has trained.
Conor is one of my favorite fighters, but Jon Jones is overall better. Striking and counterstriking is the category where McGregor is better, but everything else Jon Jones is far better:
-Octagon control
-Kicking
-Elbows from the top and the bottom
-The insane ability to beat fighters at their own game (Machida, Sonnen)
-Stamina (5 rounds vs Gustafsson and he was not gassed)
-Grit (he can take a beating and will still win
-Jerk personality which really helps in lead ups of fights
-Funny though
-His takedown defense is strong
-He can take fighters down or wherever he wants in the ring actually
Had he not had all that side bullshyt.. he'd be the champ right now and Cormier would be off our radar, he would've retired by now and be a full-time analyst and coach.
