Well, they were a lot more high-tech than those in the OT. But you have to admit, the lightsaber duels fought in the OT were between old men and a boy who had barely learnt what a lightsaber was, let alone, how to use it. The ones in the prequels were between people who were young-ish, and knew what they were doing.
I like the PT ones better. I especially like the two Yoda duels. It's really quite funny to see him in the OT, then watch Attack of the Clones or Revenge of the Sith and see him jumping around the place like a jack-in-the-box on a sugar high.
