Why do so many people like Aliens more than Alien?

Is it just me, or do most fans of the series put Aliens above Alien? It’s subjective I know, but I still don’t understand it. They’re both great films, but Alien is so much more realistic, artistic, creepy and well acted/written/directed. A far, far more effective dark sci-fi movie. Aliens has good sci-fi still, but the writing sucks, the aliens look like crap most of the time and the acting is SO cringe except for Lance Henricksen as Bishop. Sigourney Weaver’s performance is so corny and never believable, which is weird considering how good she is in Alien. Plus, it’s a military, whip out the giant guns movie. I just think it’s so dull compared to the original which to me is a work of art by H.R. Giger and Dan O’Bannon.
