Criterion 4K Blu-ray (not by much, caps)

From cbc:

I much prefer the 4K Blu-ray track. LaserDisc has several nasty constant hums, and even after you remove that, the detail level is on-par with the 4K Blu-ray and has a lot of crackling. The 4K Blu-ray has some variable noise reduction, but it's done well and non-intrusive IMO, I watched it with that track and was happy.

The mono on the Criterion is severely filtered resulting in it sounding incredibly muffled. It is nearly as filtered as the 2003 original Universal DVD which had extreme filtering and sounds horribly thin. The 2008 DVD remaster and original Laserdisc analog mastering are mostly left alone. The original LD master is from a worn element but otherwise sounds very natural. The 2008 DVD is the highest quality version we have without the heavy filtering and the defects of the LD master. It isn't perfect but easily the best of the main four sources by a dramatic margin. 

The existing 4K SDR restoration looks excellent, but the Criterion extras are limited and disappointing. The classic Stewart interview commentary from the LD is ported over but given a new mastering. Compared to past releases it has been very slightly noise reduced.

WB Europe 4K Blu-ray slightly better encoding than Criterion (caveat: missing Criterion extras)
