Beside this, which cut of aliens is better?
I'd say theatrical for both. The theatrical cut is actually Ridley Scott's preferred version of Alien. And while the director's cut of Aliens is mostly great, most of the extra scenes are also not needed (though I liked the stuff about Ripley's daughter).
Also Know, what's different in Alien Directors Cut? The Alien Director's Cut is the only extended/alternate version from the franchise to receive an official theatrical release (not counting the special Aliens Live event or other one-off screenings).
Similarly one may ask, which is better alien or alien director's cut?
The director's cut shortens a lot of them, forgoing subtle tension for getting to the action a little faster. The two new scenes do provide interesting changes to the storyline and lore of both the film and franchise. Ultimately, the director's cut of Alien doesn't drastically change much for fans of the movie.
How much longer is Alien director's cut?
Theatrical (117 min.) Director's Cut (116 min.)
