Arrow 4K Blu-ray > Criterion 4K Blu-ray > Kino Lorber 4K Blu-ray see caps

Three masterings of the original Dolby Stereo SR mix exist: the original Orion video releases, the Criterion (which is from their LD) and the Arrow. All three are excellent with slight mastering differences between them. The original Orion still is probably the one with the most fidelity, the Criterion is the cleanest with a kind of warm feel to it and the Arrow has a bit of both aspects. The Arrow mastering has a tiny almost imperceptible bit of audio bleeding into the surround that isn't on the Criterion. Each has their own pluses and minuses but you can't go wrong with any of them. Whatever you do though: DO NOT WATCH WITH THE 5.1 REMIX. It is another MGM botch job that fundamentally alters the impact of many scenes. It is vastly inferior to the original mix in every way.

Criterion Blu-ray has exclusive extras, Arrow UHD has the most extras of any release

88 Films 4K Blu-ray > Vinegar Syndrome

88 Films and Vinegar Syndrome have different extras

Cinema Guild Blu-ray is a good alternative (more extras).

UK > US, not sure France. UK (Artificial Eye/Curzon) has higher bitrate than US (Cinema Guild) but has boosted gamma (see here: https://slow.pics/c/L9U9r8Es).

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.

Criterion is new 2K restoration, but wrong aspect ratio (1.85:1 instead of AR 2.00:1)

Warner Bros 4K Blu-ray (caps; grade on the BD was controversial)

Later Warner Bros Blu-ray and 4K Blu-ray are minor downgrades

Arrow/Kino Lorber/Carlotta all very similar

New 4k restoration but no release yet https://bampfa.org/event/quince-tree-sun
