That's actually my favorite fight in the series: Luke and Vader coming to a head, the culmination of their paths crossing throughout the series, plus Luke being on more even ground with Vader than in Empire, while also resisting the urge to turn to the dark side, all while redeeming his father. It ties in large part as to why I don't like The Last Jedi. The fight choreography in Phantom Menace is probably the best in the series, though. It strikes a nice balance between the heavy, two handed, deliberate combat of the OT and the hyper-movement of the later PT fights. There's meaning behind each of the strikes, as opposed to whatever dance moves Obi Wan and Anakin were doing in RotS.
Making Obi Wan the main protagonist of the PT and showing his growth from Padawan to disgraced Master (contrasting with Luke's arc in the OT) , while making the Rise and Fall of Anakin Skywalker the overarching theme of all 6 movies is spot-on what Lucas should have done.
