Best I've seen:
El-P (Cancer for a Cure was GOAT)
Devin (You had to be there)
Method (Good for a crowd surf)
Mos (Jumpin in different sets, playin bongos and some more shit...)
Big Boi (Great presence, dances with back-up dancers)
Curren$y (Knows every word to them rambling ass songs, weed is his Spinach)
Worst:
Talib (Voice all hoarse and shit)
Pharoahe (Did three tracks and bounced. He was the headliner)
Killer Mike (No endurance, only exacerbated standing next to El)
3k (You can tell he ain't really comfortable on stage, only exacerbated standing next to Big)
Lauryn (smh)
