How do you think the Alien films should be watched?

I've always been curious. Being an Alien fanatic there's different cuts from Alien all the way to Alien vs. Predator Requiem. I was curious as how all you Alien fans out there think these films should be watched officially. For example if a friend of yours wanted to watch the Alien films and they never had seen them before which cuts of Alien through AVPR would you have them watch starting with Prometheus and so forth what cuts would you choose from each film for them to watch. Prometheus- One cut Alien- Theatrical Cut or Directors Cut Aliens- Theatrical Cut or Directors Cut Alien 3- Theatrical Cut or Assembly Cut Alien Resurrection- Theatrical Cut or Directors Cut Alien vs. Predator- Rated cut or Unrated Cut Alien vs. Predator Requiem- Rated cut or Unrated Cut
