I'm going to assume DoE Bane is the entity in question here?
Sids has already beaten Yoda, so going to have to go with that the majority of the time.
Argued for Bane against Mace whether with or without orbs, and Bane won by a margin in the thread debating that specific match up
We know that Obi can take Sith Anakin, so that leave Obi vs Sids & Bane, either of whom is more than his match in both sabers and Force, especially arcane techniques.
This is classic argumentum ad populum, and as such has no real merit.
Not to mention, some of us are still not convinced if DoE Bane can take Mace (I deliberately leave RoT Bane vs Mace for some other time)
The Jedi team might be able to take this 5.1/4.9 but it's almost too close to call. Windu's Vaapad amp will be an important factor in this fight considering the dark siders he can draw power from.
Well I myself have already argued my p.o.v. in that thread and give Bane the edge over Windu, though I agree it will be a near thing if it stays close in.
My assertion remains that more often than not it ends up with Sids & Bane taking on and killing Kenobi.
Really, I could throw that out because if we don't have the situation of Anakin out of sorts because of his worry over Padme, he certainly would have a chance of being focused enough to overcome Kenobi.
