What about Jedi Rocks?
I’d probably go with that or the Jabba scene, because no matter how much scenes like Han shooting second and force ghost Anakin ruin the characters, at least they are short while Jedi Rocks and Jabba at the Falcon are rather long. The Jabba scene basically being a rehash of the Greedo scene ruins the pacing and Jedi Rocks makes me cringe, so they affect my viewing experience more directly than other changes that ruin the movies only by implication.
Nevertheless, I wouldn’t want to watch that version, either.
