Darth Vader is by far the most powerful sith lord because of his potential, and he still fulfills his destiny and takes down the sith. With that being said he reached his potential, and became powerful, and was able to join Yoda and Obi Wan in a method of the force that Yoda taught Obi Wan.
From the movies alone, no canon. Jedi - Yoda is undoubtedly the most powerful of the Jedi because he tells Obi Wan in episode 3 that he (Obi) cannot take on Palpatine. Anakin Skywalker is also very powerful and would've probably become the most powerful had he prolonged his study of the light side.
