Alien & Predator: From the Best, to the Worst

Just like the thread I made for the Star Wars movies, but instead of those, here you can vote for your favourite Alien/Predator/Aliens vs. Predator film and also rank all the movies you've watched from this series (descending in order from your most favourite to your least favourite). I've got my rough list below, but it's rough because I haven't got the best memory and my opinion about these movies changes often.

1. Alien
2. Aliens
3. Predator
4. Predators
5. Predator 2
6. Alien vs. Predator
7. Alien 3
8. Alien Resurrection
9. Aliens vs. Predator 2: Requiem
