PoD Bane: Vader stomps, 10/10.
RoT Bane: Bane wins, 10/10. Vader is more powerful, but he isn't so much better that he could kill Bane with Telekinesis or Mind assaults. He has no Lightning either, and without super-force power or Lightning Bane can't be killed.
DoE Bane: Vader wins a good fight, 8/10. Better duelist, stronger, more durable, faster, more powerful.
