Radiance

Radiance 4K Blu-ray is superior to Kino Lorber 4K Blu-ray, see mfunk9786 review:

Despite being at a considerably tighter bitrate than the Kino, the BD-66 from Radiance /Transmission is the release to own. Looks fantastic (FiM again), grain pattern is crisp, and the repeating scene error isn't on it, either. Really nice packaging that isn't as beefy as a Second Sight LE is another big plus.

Though note its different color grading from the IP-sourced but poorly compressed Fun City Editions US Blu-ray (caps)

Judging from spectrograms at https://forum.blu-ray.com/showpost.php?p=23933756&postcount=57, Fun City Editions US Blu-ray appears to have marginally less filtering than Radiance 4K Blu-ray (whose padded 16-bit depth is a non-issue). There are also loudness differences, though it's unclear whether dynamic range also differs. Caveat: need to A/B both tracks to confirm, but no one has posted actual A/B impressions.

> Shout! Factory 4K Blu-ray (FiM encode on Radiance compared to Duplitech encode on Shout! Factory)

Radiance 4K Blu-ray > Blue Underground 4K Blu-ray

Radiance 4K Blu-ray from nic:

Unadvertised HDR10 grade that looks better than the equivalent Blu-ray it's packaged with, grain rendered very clean even when it's heavy. FiM encode so surely it's better than the Media Blasters UHD, but there are still issues with frame stability, some shots have this jitter that kinda hurts to look at. Not a night and day upgrade over the Blu, but it's better and despite its issues, probably the best it'll ever be.
