^I'm pretty much on board with your ranking in terms of least terrible to most terrible.
As for the first category, the lightsaber and landspeeder alone would have been reasonable repairs for re-releasing a film on its 20th anniversary. I probably didn't learn that the '81 crawl wasn't the original until 1995 when someone explained it to me, so the change has never really made my skin crawl. The sandcrawler is one of those changes that I'm still against in principal, but man, the new shot looks good.
The new song might be better than yub nub, but it's too weird to change the music in the very last scene of the trilogy. And the visuals, with all the extras standing around awkwardly in front of green screens with wonky cgi backdrops pushes the scene into the "No" category for me.
The only ranking here that I 100% disagree with is the Sarlacc. Really awful CGI. As a kid, I liked the mystery and absurdity of some powerful and ancient, shapeless beast that exists somewhere in between the definition of monster and scenery. Now it's a weird smooth and shiny bird thing in the ground.
