Imprint Blu-ray not only has the best encoding, but also has the "correct" aspect ratio compared to ClassicFlix which is horizontally stretched or Eagle Pictures which is squished see DVDBeaver caps

New 2k scan with very different color http://www.dvdbeaver.com/film3/blu-ray_reviews55/nothing_sacred_blu-ray.htm  but overall much better compared to the older Kino Lorber Blu-ray

MoMA has just scanned from the original separations, and it's the only version of this classic with accurate Technicolor. This new restoration is now streaming on Criterion Channel

MoMA has 4K restoration

Kino Lorber Blu-ray suffers from the Quicktime Gamma Bug see caps

Both the Plaion and Arrow audio tracks sound like they received little/any high- or low- frequency attenuation, but the audio on the new Kino Lorber restoration is much more detailed. It's likely that it was transferred from different (superior) analogue elements. It sounds excellent.
