Condit may have faced tougher competition on average, but even with all those opportunities he probably hasn't subbed anyone as difficult to finish from the bottom as Bendo and Roller.
And look how many rounds he's been in, in his 9 UFC fights, none of which he's finished off his back. He's been in around 27 rounds. Pettis has only been in around 21 rounds in 11 Zuffa fights, 4 finished off his back. Condit has a couple solid finishes off his back in Zuffa, over Larson and Prater, but that's going all the way back to early WEC days, adding many more rounds. Then, Pettis finished Mike Campbell off his back too.
And who is on their back more? Pettis has better TDD than Condit.
Defensively, Pettis is on another level. He may have the best defensive guard in MMA. Like on the feet, he's barely taken any strikes in his career. Condit's defensive guard is pretty good, but he's taken some gnp over the years. He has more trouble keeping opponents in his guard and controlling wrists.
The answer is Pettis. It's only Condit if you're nostalgic. Pettis has evolved past him on the feet and the ground as the younger and more athletic guy. They are my two favorite fighters, but it's the truth. Pettis is next level MMA.
