Just as summary for ROTJ. Someone will like it, some other will don’t. These are my ideas for ROTJ, maybe Adywan like or feel inspirated:

In Jabbas palast where we see the first time Landos face behind the mask: This scene is too long. Only a short view on the face is enough. Its senseless to enter undercover the palast and show the face for many seconds.-
The emperor said that Lukes saber looks like Anakins … but it looks like Obi-Wans.
Vader to Luke: Obi-Wan thought as you … Padme thought as Luke
At the end, when Luke looks to the Jedi ghosts, in the original version he did a small wink with his eyes. Thats very individual, I like this … but its missing in the SE.
The Jedi ghosts … I don’t like Hayden Christensen as Anakin in ROTJ too. But please give Sebastian Shaw the clothes from the Hayden Christensen Anakin from ATOC/ROTS.

Deleted scences:
I agree that the deleted scenes for ANH and TESB didn’t match into the final movie. But I ROTJ its a little different

Luke building his lightsaber: this scence have some kind of magic. Its hard to describe.
The death star want to destory the moon of Endor. These scenes give the final attack on the deathstar more dramatic and show one more dark side of the emperor
The bunker rush is cool action but not specially needed.
Same to the scence where Vader want to go to the emperor.
