Alien/AVP watch order

I've been wanting to rewatch the Alien and Alien V Predator movies. I have seen most of them, but I want to watch them 'in order'. What kind of order I don't know. Would it be best to watch in order of release date or chronological order? Or some other way?

Let me know your thoughts, and why you think it's 'best'.

Aaaaand...GO!
