Yeah I ment alien ('79) I didn’t realize I said aliens until it was too late. Up until probably like 3 years ago I would have said The thing. I think they are pretty much identical quality, both fantastic movies. But now days my answer would be Alien. Simply for the fact it might be a little more rewatchable only in the sense that I only ever really watch the thing during winter. I can be in the mood to watch alien any season.
