To me, the AVP ship looks far more futuristic than the one in Predator 2. Just by watching how the yautja prepare themselves for their hunt gives the people a Star Wars feeling about the movie. Now to the original design of the Yautja Spaceship interior in my oppinion, looks just like an evil lair, but, an evil lair that fits their discription as a race who is use to humid evironments (The fog.) and with signs of tribal characteristics. (Markings on the Wall.)
Even though we never saw very much of the exterior of Yautja ship in Predator 2, however we did in AVP. Just by watching the ship sailing silently into sight from the darkness of space was an awe giving effect towards the yautja race, instead of rapid flashes of light and a loud roar of the engines in Predator 2.
Hint: Compare the AVP and Predator 2 Endings when the ship takes off.
If I have to choose between the two ships, I would really have to go with the AVP one, just because the craft looks intresting to me. -nods-
