For the longest time I was on the Heath side of this argument. Over the past few years, however, I've had the opportunity to view a pop art exhibit in Dallas that included a Lichtenstein and a full Lichtenstein exhibit in DC, which included not only numerous examples of his pop art pieces but his other works of art too. I am now in the Lichtenstein camp. If you have not had the opportunity to view a Lichtenstein painting in person, I highly recommend it. I was surprised how taken I was by the art and its presence in the room.
