Whew, what a tough call. I don't like either movie very much although I do enjoy some fight scenes from both. I would say overall the original was the better movie, but the sequel had a better premise. I thought a good director would have really made the premise of a cleaner predator purging an alien outbreak on Earth enjoyable. The first one had better camera shots, (and you could actually see what was going on!) plot, and writing. Don't get me wrong, I feel that it was lackluster, but less so than it's successor.
