It took me a while to admit that as well but that’s more to due with the growing problems I had with ROTJ while my opinion of TFA stayed relatively the same. I think a good fanedit of ROTJ would be on par with the theatrical version of TFA though.
No fanedit can fix the Ewoks and their defeat of the Emporer’s* best troops.**
It can reduce the Ewoks and fix other things like the “Somehow I’ve always known line”, Luke instantly finding out that he has a sister out of nowhere", the droid torture scene etc. and there’s only one man who can complete such a task.
A good TFA edit would be too much for any version of ROTJ though.
