My only edit would be to put Yoda above Luke and Anakin. While he lost to the emperor he actually fought him, vader sneak attacked the emperor and luke laid on the ground writhing from his lightening. I concur that Sidious was the most powerful sith, though I think Bane was > than Sion. Just some thoughts. I have to agree that Revan wasn't the most powerful JEDI even though I enjoyed KOTOR immensely. Glad to see him make the list though.
