Jesus had the blood of God.
Sith Governor had the blood of Bandon.
They're not even comparable. As Lucein said:
"But standing above the rest is the great one, the paragon of perfection itself: Bandon. He doesn't truly belong in the ranks of the greatest Sith, as he transcends all such trivial ideologies. He exists on a plane beyond our own. His Hyper Force Push will reduce any meandering Sith officer and his console to atoms. His mustache and goatee can only be described as "wicked awesome!" It's known that he only allowed Revan to "defeat" him out of respect for Revan's hair (itself described as flowing, elegant, and dandruff-free)."
Palpatine, Yoda, Snoke, and Plagueis are probably the biggest badasses in the universe right now. Mace and Vader probably aren't all that far behind, and I'm guessing that Bane and Luke are around their level (unless they go the super-powerful Luke route). Shortly behind them should be the usual Anakin, Obi-Wan, Dooku, etc.
Of course, all the stuff regarding unknowns is unknown so it's kinda pointless discussing it at this point.
