For TFA, I’ve gotta go with Nev’s Starlight edit. I have no idea if it’s shorter than the original movie, but it is a better paced, more fleshed out version of TFA.
I don’t really dip into edits of TLJ, but you can’t go wrong with HAL’s edit. It’s shorter by 9 minutes while keeping the story the same. A similar edit is poppasketti’s, which shaves off three more minutes, tones down humor if that’s what you want, and seeds the idea of Palpatine’s return.
For TROS, I heard on fanedit.org about an edit of Spence’s TROS edit, The Final Order. Spence’s original edit is already shorter than the original film and makes things more focused by keeping Rey a nobody & killing Leia off in the beginning. Apparently, the re-edit of Spence’s edit improves things further by having Kylo’s first be him mourning his mother, so it sounds like it’s worth tracking down.
