I think ROTS (especially fan edited) is easily on par or better than ROTJ or even TFA in some aspects.
ROTJ beats ROTS (plain or fan-edited). ROTJ fan-edited definitely beats ROTS (plain or fan-edited).
What ROTJ fan edit ? Real question: I’m very fond of ROTJ but I’m interested by an edit that could correct minor silliness. Even if to my view ROTS (as a fan edit) is a good and enjoyable movie, ROTJ will always rank higher (the fun Jabba overture, the moving Luke-Vader-Palpatine confrontation, some parts of the Endor subplot, and the action packed space battle: very good stuff).
