First off, blowing smoke just for fun is not retarded at all, and I hope you were joking about that statement. I don't know too much about the differences between those boxes, however may I suggest looking at the TST. Thats what we have decided to use on an 06 we are building, because of its adjustability and because many people report great success with high horsepower numbers with this box. However, with any of the three of these, unless they come with an outlook monitor, gauges are a must.
