Question: is vader more powerful than palpatine?
Answer: Sidious is more powerful than Vader- in the suit. Anakin, pre-suit, had the potential to be twice as powerful as Yoda or Palpatine. ... Since Darth Vader is “more machine than man,” he lacked the amount of midichloriuans to adequately communicate to the Force, and so, was unable to become more powerful than Sidious.
