Most of my safety stops are done in a horizontal position because they are spent at the top of the reef still looking at critters. If I am in blue water I will do it vertically since It is really easy to hang there in a neutrally bouyant state.
I have not read or heard of any benifit for recreational divers to do it horizontally.
Cheers,
Roger
