Kinda hard to believe that Fox told James Cameron to stop writing the script for Alien 5 in-opt for the first AvP movie, but if had to choose between the two I probably would have to say Predator 3. As much as I love the Aliens franchise, I think the Predator universe needs some new life in it, since there hasn't been a movie made since the mid-90's. Even though Predator 3 is supposed to be a remake, the only reason why I say Predator 3 is because I want to see how a pack of Predators hunt and coordinate.
