For Ep 1/2 I think Hal’s latest iterations are near perfect: they still feel and look like real movies, with almost nothing which sells their fanedited nature. Ep2 still retains bad (but not THAT bad) stuff to avoid jarring cuts. If someday Lucasfilm releases finalized deleted scenes, Ep2 could be as perfect as it could be I guess. Ep1 is near as good except I still feel that the first meeting with the Gungas is missing (I’m on the other hand ok with removing the long and boring journey to the planet core).
For Ep3 not sure which one is the best as I think I prefer the theatrical cut enhanced with the deleted scenes (unlike Ep1/2 I do like Ep3 as a good movie with many flaws but with many qualities we don’t find in SW latest entries anymore). The best cut would be the extended cut with a few things removed borrowing from various fanedits. Octoroxx was working on something which could be that near perfection I guess.
