Kris Holm Fusion Freeride vs. Qu-ax air saddle

I am aware that a Qu-ax air saddle is not filled with air, but is called an air saddle due to the whole in the center and the cutaway in the front middle. As a result, it seems as if it would be very similar to a Kris Holm fusion freeride saddle.
I am wondering if anyone knows which one is more comfortable for long distance cross country MUni.

KH freeride. is great a lot people use then. the 09/10 ones are better because they are allen bolt onto the seatpost so you dont have the dome nuts to play round with
