Criterion 4K Blu-ray or BFI 4K Blu-ray

No clear winner, Criterion SDR 4K Blu-ray has better defined grain and is cleaned-up more thoroughly. But looks grayer and flatter in daytime scenes. BFI 4K Blu-ray's HDR/DV is better in contrast but the grading can be debatable.

BFI 4K Blu-ray

BFI 4K Blu-ray has excellent master and grade, no DNR and tasteful HDR

Toho Japan 4K Blu-ray's OG Perspecta & mono (filtered but still sounds better than unfiltered 2009 Toho Blu-ray).BFI 4K Blu-ray has OG Perspecta (in 5.1 container) and stereo downmix of it; no original mono.

The way Perspecta works is it just changes volume and panning of the mono across L/C/R channels depending on embedded control tones, so realistically all mixes are just the mono, but it's still a big shame that we get a stereo (presumably a downmix of Prespecta...?) rather than than proper mono.

Grain is sharper/clearer on the new Criterion 4K; BFI's grain resolves slightly worse and more so in motion, being a standard Blu-ray; The Toho 4K's grain is softer, probably DNR'd.
