I like both pretty much equally, though if I absolutely had to choose just one, it would be Terminator by the smallest of margins. Terminator was a more visually striking film, and the chase at the end is intense, virtuoso action film-making. Robocop was fun, often funny, and had a social message behind its cheesy 80's exterior. Both movies had great theme-songs and memorable one-liners. The scene where the enforcement droid still shoots the guy after he puts down the weapon in the board-room is flat out hilarious.
That brings me to a question. Why the hell isn't Robocop's poll quote: "Dead or alive, you're coming with me."?
