I own every edition of Blade Runner on LD, nine of them in all. US Theatrical Cut, European Theatrical Cut, Director's Cut, pan & scan, letterbox, analog sound, digital sound, American, Japanese... I've got every combination.
The two best laserdisc editions are the Criterion CAV (European Cut) and the Director's Cut.
Krynos, the DVD is not the same transfer as the Director's Cut LD. For one thing, it's anamorphic. It also has a much better black level and a better sense of detail. Unfortunately, being the very first commercial DVD ever released, the compression quality is a mess by current standards and it definitely needs a remaster.
