Probably the moon, just because it's closer and would be easier and shorter trip for transporting equipment. It would require less fuel, less oxygen on the ships, and so forth.
There was a pretty good plan for colonizing Mars a while back, but I think NASA rejected it for some reason. It takes like 6 months just to get to Mars from Earth when the two are at the closest parts of their orbits. For a trip like that, we'd need a space craft design right out of Star Trek to keep the astronauts from going stir crazy.
