I thought ROTR was an absolutely awesome experience from a total ride perspective. However, I was so disappointed in the final two movies of the new trilogy that the story of ROTR did not excite me at all. When I was a kid, I dreamed of going to a Star Wars Land, I find myself disappointed in Galaxy's Edge though because I just have no connection to the new trilogy. I am completely in awe of what imagineering did with the ride and the land, but oddly enough, I have zero emotional connection to it, other than annoyance about what could have been if Darth Vader, Han, Luke and Leia were the stars. Of course, I know people who love the new trilogy, so your mileage will definitely vary.
With Avatar it was the exact opposite. I thought the movie was cool, but have only seen it once when it was in theatres over a decade ago. But wow, they really knocked it out of the park with that ride, I think it is the music and visuals. It may be in the same family as Soarin, but it is executed perfectly.
Tough call, and when ROTR is firing on all cylinders it is amazing. However, when your whole day revolves around this ride, and only 60% of it is working correctly, the letdown is palpable. Even worse, when you can't get on the ride, it literally can kill the enjoyment of the day.
