Duel of the Fates is really good. The music and the acrobatic performances play into the (intentional) feeling that this is something ritualistic and ancient. The gigantic plasma pillars could be toned down a lot but the huge cavernous space suggests a kind of temple. Here we’re meeting our enemy from a thousand years ago and we’re all bringing those many years of tradition with us.
The duels in Attack of the Clones are awful. Most of the Palpatine and Yoda duel, and parts of the Anakin and Obi Wan duel, are pointlessly flashy and don’t contribute to the epic feeling in the same way the Darth Maul fight does, but the Anakin and Obi Wan duel is pretty good otherwise.
As for Obi Wan vs Vader in the original movie, it is a bit slow due to the limitations of the props, but it’s still good. This guy just sped it up a little and it works very well. Much more classy than SC38 or the Obi Wan show. https://www.youtube.com/watch?v=rVqg7sTcra0
