I have PA Hud turned on when I play sng's but my main use of it is to see the hands at showdown. I like to see what someone called all the way to the river with. Helps me tell if he is a fish or not. Very hard to use the VPIP or PFR stats in a sng. After 20 or 30 hands you don't always know if the PFR was with a good run of cards or junk. That's why I like PAHUD for the showdown. If he calls on the river and wins I see his cards as per normal and if he loses and doesn't show PA HUD shows me what he had. I find it to be a HUGE advantage.
