Disney 4K Atmos is great, a reference quality track. It's a very slight remix (music seems to be from a better source), but it's completely seamless and faithful to the original, better fidelity than anything since the 1994 30th Anniversary Edition LaserDisc.
All DVDs (and 2010 Blu-ray) sound far worse than the 4K Blu-ray/LaserDisc and have various missing sound cues.

2020 StudioCanal 4K Blu-ray vs 2017 Sony 4K Blu-ray (20th annivesary) vs 2025 Sony 4K Blu-ray (Luc Besson Box Set). The first two have totally different texture.
StudioCanal: More natural looking. Better defined grain. The white balance is rather yellow/orange. Some say it is closer to the original theatrical release.
2017 Sony: More vibrant and impactful. The white balance is rather neutral. While color noise and grain can look busy because it had been sharpened and had micro-contrast boosted.
2025 Sony: Supposedly an improved version of the 2017 release? Shows around 20mbps-higher overall video bitrate. caps
2025 Sony US 4K Blu-ray has the original 5.1.
The Atmos on the Sony release is reportedly better than StudioCanal's.
Disc info of the box set discs. This film have recieved multiple encode/versions in different regions over the years. The 2017 Germany4K Blu-ray is encoded differently than the 2017 Sony but not better. Also, the same can be said to 2024 France Gaumont 4K Blu-ray while comparing to the 2020 StudioCanal 4K Blu-ray. The StudioCanal 4K Blu-ray omits all the extras from previous releases, being barebones.

The older Studio Canal disc has incorrect pitch - 0.7 semitones lower than it should be. As their PAL DVD release was pitched correctly despite running at 25 FPS, it's likely they just took that master and slowed it down without accounting for that.

Imprint Australia 4K Blu-ray has slightly better compression than Criterion 4K Blu-ray.
The master in DV looks all but identical to the Criterion’s HDR grade. Detail-wise, FiM’s encode looks like it uncovered a tiny bit of extra high-frequency information that got filtered on the Criterion. See nicolas review
1990 Criterion LaserDisc/1993 MGM LaserDisc/2002 R2 MGM DVD are the best. See blah-ray https://blah-ray.blogspot.com/2018/01/raging-bull-1980.html
Imprint Australia 4K Blu-ray has better audio than Criterion 4K Blu-ray, from nicolas:
I believe that what’s on Imprint’s 4K is one of the good mixes MGM and Criterion released during the LaserDisc days. Music is powerful and detailed, dialogues have excellent fidelity and ambient sounds have perceptible depth. I compared the "new" 2.0 with the anemic 5.1 as well as the Criterion 4K mix and could clearly hear the improvements.

Capelight's 5.1 is sourced from the original 6-track. The fidelity is comparable to the 4.0 from the 4-track available on previous BDs.
An alternate 5.1 mix was created for the 1999 MGM DVD / LaserDisc, It boasts better high end detail throughout, but the trade off is reduced bass.
See additional info for more detail.
West Side Story was produced as a 70mm Todd-AO presentation, with an accompanying 6-track audio mix in the following channel configuration: see diagram. 35mm presentations used a 4-track or a mono mixdown instead.
The original 6-track elements were thought to have been lost until they were recovered and restored in 2010. In 1981, for the film's 20th anniversary, a new 6-track mix was created by upmixing the available 4-track elements.
Capelight's release is sourced from original 6-track elements uncovered in 2010, but unfortunately it's not as detailed as it should be, owing to unnecessary noise reduction. It's by no means bad, but it could be better. As the Lc/Rc channels are mixed into into L/C/R, it's also essentially no different to a 4-track fold-down. This isn't exactly an issue as left/right center channels mix down to L/C/R very well, but a better way of handling this would be to use Atmos objects to position those channels where they should be, as Disney did on The Sound of Music.
The 4-track mix was included in a discrete form on MGM's previous BD, it trades blows with Capelight's 6-track-derived 5.1.
Interestingly, the 1999 MGM LaserDisc/DVD release includes a different 5.1 mix, which sounds a bit more detailed than the two other tracks. It's sound signature is on the brighter side, with a slight emphasis on the treble instead of bass like other releases. Although that accounts for some of the perceived detail, even after matching EQ there are spots where Capelight loses out. It's a slight upmix, with split surrounds and LFE. Whether it was derived from 4-track or 6-track elements is not clear, though it matters little, as the end result would have been very similar in either case. There are no booklet notes stating the source used, but it sounds very similar to the matrixed 1992 LD, which was attributed to the 6-track. Still, given that the original elements were thought to have been lost, I would assume that this refers to the 1981 mix.
Previous LaserDisc releases are similar to the discrete 1999 track. All LD releases are missing the intermission music and a brief whistling sequence.
The 7.1 upmix on MGM's Blu-ray offers little of value.

Arrow UK 4K Blu-ray >
Capelight DE 4K Blu-ray Kino Lorber US Blu-ray, see caps
Arrow has done additional cleanup work removing nearly all the damage in the transfer. They have massaged the color timing and HDR to try and improve what they could. The Capelight may have better encoding but it does not have these improvements. The Arrow encoding is solid and in motion there are no issues whatsoever. The Kino release has the damage and other issues plus frequent noise due to the lesser encoding.
Some scenes in the Arrow transfer are better, some better in the Capelight.
Original matrixed Dolby Stereo: Arrow 4K Blu-ray or Image Entertainment LaserDisc
(Arrow is a port of the LD track, see spectrograms) This track has the best fidelity of any release but does have some channel bleeding baked in. The 2017 2.0 on the Arrow and Shout BDs was the Dolby Stereo original mix without channel bleeding but that had heavy noise reduction resulting in a very flat and underwhelming presentation. The surround winds up being lessened as well due to the processing. It's a tough choice between the two but the Image LD audio wins out because it hasn't been messed with and the impact is so unrestrained that no other version hits in the same way.
Capelight and old Arrow BD included the original stereo mix, but with excessive noise reduction rendering it much less detailed. Kino only included a painfully defective 2.0 track sourced from somewhere with limited fidelity, volume spikes and screechy high end which frequently ruins the music. The 5.1 remix on most modern release is a processed version that does not sound as good as it once did.
The best and most accurate of the 5.1 mixes is the original version from the 2003 Special Edition DVD in lossy AC3 form.
