I think the director's cut is better and because of the inclusion of one scene near the end.
I can understand why Scott left it out but it is such an incredible scene.
But watch the theatrical and then the director's. They are both incredible.

Theatrical, but Director’s is a worthwhile bonus watch.

Theatrical cut.

Theatrical Cut, hands down.

I actually like the "Theatrical Cut" of the Movie more than the "Director's Cut" of it.

Ah! Now it makes sense.

I think The Dc was better cause it was methodical and made more sense.

The Director's Cut is good for the bonus scenes, but I much prefer the Theatrical Cut. It's a tighter experience and flows better.
So many stories, so little time.

I've only seen the theatrical cut. Need to give the directors cut a try next time I watch this.

The TC, but there are very nice character beats in the DC. Personally I'd combine the TC and DC, but exclude the cocoon scene; not because it's bad, but much like the Burke cocoon scene in Aliens, it's good yet slows the final act a bit.

It's being discussed currently on another thread so I've just copied and pasted what someone else wrote:
prbronx5replied 2 days agoSeveral scenes are cut, example, Dallas talk with MUTHR before the airshaft scene.Some are added:Transmission on the bridge.Kane pulls out a laser gun while in egg chamber.Lambert attacks Riley outside the infirmary.Adult alien dangling among the chains in the landing gear. This is during the Brett death scene.Parker and Ripley run into the landing gear room, as alien drags Brett up into the airshaft.The Dallas Brett coccoon scene.Alien slaps the cat carrying case with Jones inside.

Isn't the DC actually shorter? What did they cut out?

I'd go theatrical cut and then watch the scene with Brett and Dallas being cocooned as a kind of bonus - not that much more was added to the DC really
