Kino Lorber 4K Blu-ray > StudioCanal 4K Blu-ray

Included Imprint Blu-Ray also has markedly better image compression than the Criterion Blu-Ray, though do note the Imprint has some adjusted color grading within roughly the first five minutes of the film

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.
