Best John Carpenter Movie

Many people believe that Halloween is John Carpenter's greatest film, but I disagree , i think its a tie between Halloween 3 and They Live (Rody Piper in a good film, its an accident I tell you)
both films are similar in that they are about conspiracy theories, involving objects that people wear in their faces. In H3 its mask that will kill the worlds children Halloween night, while in they live itssun glasses that allow people to see Aliens that have taken over the earth. In both movies the hero inadvertly discover the conspiracy and try to put an end to it. I dig the whole conspiracy angle where the heroes are persued by government/corporate agents who try to eliminate them.
