I've never much liked the Director's Cut to be honest. Mostly because it lops out the "What Are My Chances?" scene, which, combined with the vents right after, is my favourite part of the whole movie.
The only change I come close to wishing was in the theatrical is when they listen to the transmission on the bridge, but then Ridley went and spoilt it by changing the original, creepy as f*ck noise to a really generic one
