The best duels are ones where the duelists have some major personal history and backstory that led to the duel happening in the first place. That’s why the duels in ESB and ROTJ are always the best. In ESB, you have Luke fighting the man who killed his father (or so he believes), and in ROTJ you have a son fighting his own father.
Also helps that those two duels had really good lighting and cinematography (especially Empire), something which I’ll admit is a bit lacking in the prequel duels.
