I will agree that the duels in the PT may be more visually stimulating and appealing, but in terms of characterization and emotion, the OT duels are way ahead of anything in the PT.
I don’t see how Dooku and Hayden spinning coloured glowsticks above their heads in extreme closeup, CGI Yoda bouncing around like a constipated frog, CGI Palpatine leaping off the walls, or Obi-Wan and Hayden twirling their lightsabers around like synchronized baton twirlers could ever be considered visually stimulating, let alone appealing.
Other than Yoda’s lightsaber duels, all of the lightsaber duels in the prequels were brilliant.
