Criterion  Blu-ray contains exclusive interviews.

The 2013 King Records Blu-ray is the only Blu-Ray release with the video processed look that appeared theatrically, all following Blu-Ray releases use an restoration straight from the original camera negative.

Shout! Factory 4K Blu-ray is more filtered than Warner Bros Blu-ray, although differences may not be audible.
(While the LaserDisc 2.0 is reportedly better clarity in dialogue?)

DV Plot. For those curious, the sculpture is still the altered one found on the re-issued DVDs, and previous Blu-ray.

5.1 audio on the Shout (either be 1080p or 2160p) was 16-bit, with more roll-off than the Warners one, the Warners was very similar to the NTSC and in terms of balance of the mix, while the Shout seems to be tinkered with, with the score at the beginning and at the end sounding worse on Shout.

Audio Comparisons: Slow.pics

For the regular commentary found on the NTSC DVD "Original Version" (there's no difference including the other NTSC DVD), Shout or Warners; the Shout commentary was just a bloated lossy transcode with some EQ. The best one was from either of the two DVDs.

Commentary Comparisons: Slow.pics

Now there's another commentary; it's basically the same commentary but has some parts different than the others, it can be found on EUR PAL DVD with subs for said commentary. The subs for it doesn't sync for the commentary #1 and vice-versa. Samples

(caveat: has a slight error)

Universal 4K Blu-ray - caps. Looks stunning against the horribly neutralized old master. Very glad Deakins supervised the new grade and had Universal restore his color filters.

Universal Blu-ray (included in the 4K edition) has the original 5.1 mix not on the 4K disc 

The original 5.1 surround mix from the 2011 USA BD was included alongside the new Atmos upmix. The compatibility track is a downmix of the Atmos. The Atmos is overall lightly remixed with noticeably more high frequencies rolled-off relative to the old 5.1. I think the 5.1 sounds better. The 5.1 mix from the USA BD was used as it sounds essentially the same as the EUR BD (with some minor loudness differences) while not featuring the dither noise and low frequency noise that the EUR has. Commentaries between the USA UHD and USA BD are the same, with both featuring Dolby Surround metadata

Audio comparison: 5.1 surround

Also known as: Leap!.

France Blu-ray has the best video and best audio for the original French version, but has no English subtitles.

Canada Blu-ray has inferior video and audio to other versions, but is the only version that has French audio with English subtitles (dubtitles from the export dub).

UK Blu-ray censors one of the songs. Australia and Canada Blu-rays present the uncensored export dub, with better audio in the former.

US Blu-ray only has the redub.

Spain 3D Blu-ray has the English export dub titles instead of the original French titles.

Universal 4K Blu-ray is just an 2K upscale of the previous Blu-ray see caps, but it does have Dolby Vision

Italy Eagle Pictures 4K Blu-ray >StudioCanal UK (slightly better encoding on Eagle?)
