F. W. Murnau

MoC vs Kino Lorber Blu-ray, where Kino Lorber is supposedly a new restoration, different tint but darker and less shadow details http://www.dvdbeaver.com/film5/blu-ray_reviews_73/early_murnau_blu-ray.htm 

Both Eureka and BFI Blu-rays are worthy of owning. Each restoration has unique positives and extras. The James Bernard score on the BFI is outstanding and the image tinting is different to how the Murnau institute official restoration was done. The Eureka MoC Blu-ray is stuffed with extras and remains one of the best-made Blu-rays of all time. Whatever you do: AVOID THE Kino Lorber Blu-ray!!! It uses the same Murnau institute restoration but drops frames for the whole feature - thus it loses a significant portion of the film! This was never acknowledged or addressed. The Kino Lorber Blu-ray remains one of the worst Blu-rays of all time for this reason.

(unsure)

Germany new 2k restoration, no subs
- US Flicker Alley not sure which restoration

Kino Lorber and MoC Blu-ray looks essentially the same, with Kino Lorber marginally better https://caps-a-holic.com/c.php?a=1&x=263&y=236&d1=11968&d2=9399&s1=118114&s2=90719&l=1&i=7&go=1

MoC vs Kino Lorber no comparison, Kino Lorber is the same old restoration

Kino Lorber AR is squished; MoC is correct. Unsure on France Potemkine

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

MoC seems to be similar to Carlotta, but Carlotta doesn’t have EN subtitles and really really hard to find

Eureka MoC Blu-ray > Kino Lorber (see slowpics for comparison). No information on Potemkine.

MoC has higher bitrate than Kino Lorber, also the contrast is increased. But there is no noticeable reduction in visible film damage presented between the two offerings.
