Kino Lorber Blu-ray is a newer 4K restoration than Imprint Blu-ray and significantly better see caps

No information on French Elephant Films Blu-ray

The 4K discs in both Criterion and Imprint sets are FiM encodes, but low-passed. The compression is better, but some of the grain is lost. Difference is pronounced in screen caps, but not likely to be noticed during playback, without a reference to compare it to. Comparisons

All discs use the same source transfer. It's not of the highest quality, and it includes some slight distortion, looping, clicks, pops, and hum. Criterion cleaned it up for their release, but unfortunately also lost a lot of fidelity in the process.

MGM NTSC DVD doesn't seem to have some of the more prominent distortion and has slightly different EQ but is otherwise the same.

The Criterion Complete Kubrick and Imprint 1953-1957 sets include remastered BDs. All standalone releases are from an earlier master.
Arrow UK Blu-ray has an exclusive isolated score & effects track. Kino Lorber and Imprint have an exclusive commentary each.

Criterion 4K Blu-ray > Capelight/Kino Lorber which has heavy noise reduction and opening snare hit is missing, Capelight is slightly better encoded than Kino Lorber

But still a bit overly noise-managed.

1984 CBS/Fox Hi-Fi VHS maybe better?
