I also do but I would never argue they're technically better movies. I'm just not interested in anything Aliens is trying to do, even if it does it very well. All I really like in that movie are Hicks and Bishop. Fine as its own thing, has zero connection to anything I like about the first movie - which I understand is in many ways what's good about it: it's so thoroughly its own thing.
Not that I count anything but the first movie as canon, tbh. I'm a defender of the prequels but its not like I watch Alien and think about how the Space Jockey is a big grey guy.
