I'm going to have to go with the first AVP. It was flawed, but it's a fun movie to watch to get your Alien Vs Predator fix. I love the look of the film, it has great set designs and eye candy cinematography. The special effects in the movie were quite impressive, the part where you see the Queen alien running through the whale bones was insane. The whole Antarctica settings was great I thought, it added to the atmosphere of the film. Grid vs Celtic was awesome, Queen Vs Scar was epic, Lance Henriksen being in it was a plus too. The only problem I have with the movie is the fact it's was PG-13.
AVP-R on the other hand could have been atleast a bloody, fun, horror flick but it just ended up being choked to death with poor, washed out, boring visuals that destroyed every single shot and scene in the whole f--king movie.
