All right back to this:
One thing that I like better in TROS than ROTJ is that Rey actually defeats Palpatine by acting out Yoda's teachings from ESB. Yoda never told Luke "a Jedi uses the Force for knowledge and pacifism, never for attack." He said to use the Force for knowledge and DEFENSE. In my mind the "proper" way that Luke was supposed to defeat the Emperor was by deflecting the lightning like Rey did. As soon as he tossed his saber I can imagine the ghosts of Ben and Yoda instantly doing a double facepalm, lol. "Kidding me, you've got to be," lol.
Now obviously Vader coming to his aid was epic and made *his* character a total badass at the end but Luke's go to defense always seems to end with suicide, lol. Suicide on the Cloud City gantry, suicide against the Emperor, suicide on Ahch-To.
And then the other way that TROS' finale trumps ROTJ IMO is that we really do see the galaxy respond to oppression in a definitive and sustainable way with the mobilization of the zillion ships. ROTJ ended with the tiny Rebellion getting all the credit while the defeated galaxy got "rescued" from the Empire. But with TROS we saw able bodied ships from every conceivable system joining together in a way that can be repeated forevermore should an evil force rise from within or outside the galaxy going forward. And that's another reason that I just don't think that there's really any story left to tell post-TROS.
