Universal Blu-ray seems to be an old HD scan and doesn't look too good

The audio on the Kino Lorber Blu-ray comes from a better source than the various DVDs and the previous HD version on streaming. This audio is relatively untampered with, and is likely the best available source as no laserdisc was ever issued.

MoC audio is better https://forum.blu-ray.com/showthread.php?t=225532&page=3

Spain Universal Blu-ray is from a very soft DVD-era transfer; caps

Criterion 4K Blu-ray is a new transfer by UCLA, with a bit more high end detail

The earlier transfer used on the Spain Universal Blu-ray and MoC DVD is a bit boomy with boosted bass. The 1999 Criterion DVD uses an even earlier transfer with noticable artifacting and less detail.

Spain Universal Blu-ray has older MoC extra "Kent Jones and Dan Sallitt on Trouble in Paradise" with MoC watermark, and no other extras

Germany Plaion Blu-ray > UK Arrow > France Carlotta All three use the same source but all very minimal difference.

There is no comparison with Criterion Blu-ray

"a full frame 35 mm fine grain positive was scanned at 4K at an historically appropriate 21 frames per second. Following this, more than 160 hours of digital clean up was completed at 2K"
