Why did you bump such an old thread?
Regardless, In TK, both are roughly equal. I have never seen any telekinetic feats from either that would suggest they have the advantage. In Speed, obviously, Anakin has the edge, and that is the main reason he should win. When Maul and Vader dueled, Maul was leaping around Vader, slashing him repeatedly, and if I remember correctly, Vader never even landed a hit on Maul until the end when he nearly committed suicide to win. Anakin has greater speed feats than Maul does and should be able to replicate that. In resiliency, clearly Vader is more durable. He survived a Dark Side Burst and has fought with multiple saber wounds before, but Anakin should still be able to down him. Telepathic abilities may be more refined on Vader's part though. I have seen him straight Mind Control others before, while I never have with Anakin. However, Vader is not some extremely powerful telepath or anything of the like and rarely uses Mind Control during combat; so it may not matter. Lightsaber Throw, I know that both of them have learned it. Vader has used Beast Control, which I have never seen Anakin use (one of the powers I think Vader has that Anakin doesn't), but it makes no difference here. Vader is proficient in Absorption and Deflection (another power he has Anakin never used, that I remember), but that would be of no benefit to him here. In dueling skill, that may be hard to say. Vader could possibly have a skill advantage to his control and experience, but with Anakin's speed, that would not be enough for Vader to win.Thus, In regards to Legends,I believe Anakin takes it about 6-6.5/10.
In regards to canon, Vader has been unquestionably written to be Anakin's superior, and does possess superior feats and accolades regarding force prowess. In terms of dueling skill, Anakin has an edge over Vader both in feats and accolades. Still, Vader probably takes it about 6/10 times.
