I've always liked the looks of the 1A better, probably because my first exposure to any Pershing was from the Estes catalog and knowledge of the 2 came much later.

However, I'd have to think about it a while based on your criteria. Obviously, the 2 has much better capabilities, but this is more like the Military Channel's top ten shows where you rate it based on what else was available in comparison and how much impact it had at the time it was in service.
