It's between Akuma and Sagat.
Akuma is the shit because he can juggle all night (with so many setups), and he has the best super in the game - raging demon -. If he had more stamina he would def be top tier.
Sagat is a fucking beast.
....
his guard crush strings, reach (mk?!?!?!?!? to name one), and overall damage makes hims a beast.
