I think your comparison is unfair.Enforcer Talen wrote:but both in their prime - anakin in ep2, luke in ep6.
According to the films, Luke is in his prime in Episode 6 RoTJ. This is a simple enough observation, he has had a lot of time to train and prepare himself.
However, the same cannot be said of Anakin in Episode 2 AoTC. Since we do not know the details of the extend of his force powers or lighsaber skill in Episode 3 we cannot be certain he yet has reached his prime. It is likely that Anakin is going to be very powerful in Episode 3, much more so than Luke in Episode 6.
That being said, the only fair comparison would be Anakin from Episode 2 and Luke from Episode 5. And in that contest I would bet firmly on Anakin.
