[edit] He beat me to it...
With the HP you'll drag the driveshaft on a whole lot less stuff because, obviously, it's not at the lowest point of the axle.
The other benefit, and probably more important to a lifted short wheelbase rig, is less driveshaft angle so it's less likely to bind with articulation and also less u-joint wear.
