kmd,
I think the only real advantage of using a 4 stage pump over a 3 stage pump is the decreased effort required to stroke the 4 stage pump. Sort of like riding a 10 speed bike, the lower gears let you go up an incline easier with less effort but you must pedal more. 
Stroke for stroke, the 3 stage pump probably puts out more air/stroke then the 4 stage pump.
