It depends on the asteroid (iron nickel asteroids wouldn't be good candidates, for example), but a key difference is how the moon was formed. NEO asteroids originally come from the main belt, and from meteorites it appears some would be decent sources for volatiles. By the way, that doesn't mean iceballs, but minerals where you would at least some carbon, hydrogen, and so forth..
