2012 Blu-ray is of similar fidelity but adds extra foley sounds. 2003 PAL DVD is a stereoized remix.

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.

As noted at Blah-Ray, the mono mix on the Fox Blu-ray, although not perfect, sounds better than the 5.1 remix and at least as good as earlier LaserDiscs, which suffer from being murky.

1988 MGM/Turner Hi-Fi VHS: Detailed and natural.

2008 R1 Warner Bros DVD - Frank Sinatra Collection: More muffled due to noise reduction.

2015 Warner Bros Blu-ray: Like the DVD but with a treble boost. Also a lossy transcode.

Full review from blah-ray

An undeniably significant improvement from the BD yet still severely flawed. See DFIC's review.
