The 4-2-1 is more for evenly distributed power while the 4-1 is for top-end power.
If you have any auto, I would recommend the 4-2-1. Batlord got good gains with it on his Tibby. Most people I have seen get the 4-2-1 headers.

Like Phantom Said.
The 4-2-1 is for more midrange, and reccomended for autos.
The 4-1 moves the powerband up top, and is best for 5-speeds with other N/A mods or a supercharger.
