In the context of duels I really like Vader vs Luke in ROTJ, as when Luke overwhelms Vader you can tell it is from pure rage induced strength. It has a very visceral feel. Clone Wars took some time, but they did have some fantastic duels as well.

I really hope that the hinted at duel between Kylo Renn and Finn is a one sided beating like this:
I want to see how dangerous Renn is, with Finn needing help to even just survive and escape. The feeling of seeing Vader blocking blaster fire with his hand in TESB is the kind the kind of menace I want.
