7. TFU Vader
8. RotJ Vader
9. Knightfall Vader

Falls at 1.

1 should be higher. That said, Bane could probably make it to Dooku, although a case could also be made for him losing to Maul.

There's no case to be made for him beating Maul, however I may give him the nod over Ventress.

Durge outlived Vitiate and Plagueis. These two idiots kept delving in the dark side: And the answer was in front of them all along.
Possess a Gen'Dai.

4 or 5

Not sure if he really could beat Durge. I suppose if he pulls a Kenobi or Anakin and abuses his TK heavily enough.

Might lose to Maul. If not, he loses to Dooku.

6 if Grievous is canon
