ROTJ Vader and ROTS Sidious vs ROTS Yoda and Obi wan

Vader goes back in time to take revenge and his face his old Master in his prime.

Vader fights Obi Wan in the same location that he fought Anakin.

Yoda fights Sidious in the same location Sidious fought Mace.

Who wins?

1. Vader should take Obi seeing as how he's supposed to be much more powerful and i guess hindsight being 20/20 and all.

2. This one i really don't wanna get involved in.

I agree I feel Vader should win.

My take on the Sidious and Yoda battle is that Sidious would lose to Yoda. I believe the environment was helpful to Sidious in having a stalemate battle with Yoda, but in this environment Sidious would not have that advantage.

Vader

Yoda

Vader

Sidious

Dark Side always wins in the end

Obi Wan.

Yoda.
