The Criterion 4K Blu-ray has marginally better detail and grain structure than ESC 4K Blu-ray

The ESC France 4K Blu-ray is an SDR grade erroneously presented in HDR, but if your player can force the HDR into SDR it looks very good.

2011 Criterion Blu-ray has the least tampered with audio of the DVD era, but it's possible the 1993 Criterion LaserDisc or the 1998 Japan LaserDisc are preferable.

2021 StudioCanal Blu-ray has better encode and gamma levels compared to older StudioCanal Blu-ray caps

Criterion and Coin de Mire are both based on the same new 4K restoration. They have close quality, but Criterion has thiner and less blocky grain, with better retention in dark areas. It was therefore preferred.

Criterion and Coin de Mire are both based on the same new transfer which is superior to the old master. But, again, the audio of Criterion has much higher dynamic range than that of Coin de Mire and was preferred.

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

Kino Lorber 4K Blu-ray is a fine release with no glaring encode issues, the new master is also fine but graded to look quite dim in HDR/DV. Unsure whether that's really respectful to the source

Old Warner Bros US release is inferior.

No comparisons but Cohen is the only Blu-ray that's English-friendly
