As great as the last 1/3 of ROTJ is, the middle 1/3 is equally dull. ROTS is solidly entertaining through out and for me, the battle between Obi-Wan and Anakin is a standout of the entire series. Ewan McGregor is always great as Obi-Wan but he absolutely nails it in the final battle. And while he was goofed on for Attack Of The Clones, Hayden Christensen comes through in the climax too. The fight between Yoda and the Emperor is cool. The score basically bringing together all the great music from the prequels makes great scenes even better. All that makes ROTS better than ROTJ for me.
I'm happy for you Travis. I really wish that I liked ROTS more than I do, but I find the ham-handed direction, the leaden dialog and IMO the lame "turning" of whiny Anakin to be less than compelling cinema. While the new films certainly have their own issues, for me they feel much more like Star Wars than any of the prequels ever did. The five minutes of Vader bad-assery in Rogue One almost makes up for it though. Almost.
