Horizontal on both ascent and descent. With proper finning technique it's a lot more comfortable and easier to maintain proper boyancy in a horizontal position. I'm with DRE on the PADI descent, it's a good way to slam into the bottom and send up a plume of crap. I also use a head first vertical descent like DRE for a more rapid way of getting to your desired depth, though the speed of descent needs to be kept in check as rapid descents increase the severity of narcosis for deep diving.
