Now that the trilogy is finished, I gotta say the D+ versions by Oohteedee are definitely the go-tos. Maybe the stuff Harmy and Dre are cooking up for Despecialized v3 will top that due to the combo of Dre’s grades and Harmys abilities with mattes, rotoscoping, etc… but for now, using the 4K UHDs as the base and the 4K77/80/83 raw scans as the sources for replacement shots/scenes:

Star Wars D+77 v2.3
Empire D+80 v2.2
Jedi OTD83 v1.0

That’s the OT for me for the foreseeable future. Despecialized might change that, but these versions are as good as the original Star Wars has ever looked and sounded on home video.
