I agree with tarmix, when cutting in a new bevel or doing some larger repair work, I use back-and-forth strokes because you are working almost twice as fast and the final condition of the edge is not established yet. But in the final honing step I use only a trailing edge motion (this is on waterstones).
On a very hard hone, such as a ceramic hone or some oilstones, there are times though when I prefer a leading edge motion. You really have to try both to figure out what works best for you.
