Well, it's mostly there in the subject. I think Apocalypse's aliens sucked in comparison to UFO's aliens, in all capacities. I preferred the art of UFO to Apocalypse, and the way the aliens work is just lame in Apoc too. I mean, what's with half the aliens having built in guns? and aliens that run up and EXPLODE on you? Unless it's incredibly cheap and easy to clone those Poppers, no self respecting alien would bother with them when heat seeking missile or even that alien proximity grenade would do the trick. 
Also, the aliens just look goofy in Apoc. You got those big blue Cookie Monster looking guys, and the stupid purple straw-head guys, and the Big Birdish skeletoid guys, and the brainsucker things that really just looked like little piggies. 
The only cool alien is the giant worm thing, and I don't see why or even how that thing shoots green crap. It would make more sense for it to just run up and munch on you. And would look cooler too. I kinda like how it pops open and makes little aliens. 
The brainsuckers are dumb. What we really need is to have those big black insect guys from UFO back. Those things were very close to truly terrifying, at least for me. The alien I miss the most is the Sectoid, though. Sectoids rock. They are SO necessary. and Mutons. And Snakemen. Well, that's my main gripe.
