2017 JP Kadokawa Blu-ray has the best encoding out of all the older discs.

Kino Lorber and Artificial Eye Blu-ray use the same master, between the two the PQ on Kino's release is slightly better, but the difference is negligible. However, Artificial Eye also includes the 2.0 stereo mix in addition to the 5.1 mix, while Kino only includes 5.1 mix.

The 4K restoration (Criterion, 4K etc) are cropped to 2.35:1, have revisionistic colour grading and other changes.

Caps: old master, old master vs 4K restoration

Wong Kar-Wai on the framing:

With Fallen Angels, I have changed the format to cinemascope, because it was originally what I had intended to release the film in. When we were cutting the film, we accidentally turned the Steenbeck on anamorphic instead of standard. I felt that the film looked much more interesting because it enhanced the distance of the characters on top of the extreme wide angle that we shot on. Back then, it was impossible to shoot a film in standard and release it in anamorphic. With this restoration, we have successfully fulfilled this wish.

UK Arrow 4K Blu-ray > US Shout! Factory, better encoding by Engine House and redone opening credits, errors present in Shout! Factory fixed

Mono is from an alternate higher fidelity source than Shout! Factory.

Good 4K Blu-ray upgrades of Ritrovata's flawed restorations

Different color gradings, 88 Films disc is encoded by FiM but Vinegar Syndrome encode (by Marcus Johnson) is more than robust

Vinegar Syndrome potentially has better audio than 88 Films, due to VinSyn possibly having EQ'd the audio mix after Fortune Star scanned the track in a way that makes it sound too hot, whereas 88 left it alone without addressing that issue. However, no direct comparisons exist
