First of all I have to say I don't think any method is more deceptive than the other. I've seen PS and SS which both look absolutely convincing.
However for general magic purposes I'm with Roberto Giobbi and find the pushoff second a bit more useful. I don't do any routines with rapid and long dealing procedures, where the strike second would be better (for me).
I can hit a pushoff second every time (I prefer Andi Gladwins/Ed Marlos Master pushoff technique) but it's not as reliable for fast dealing as a Strike for me.
However the most important part is conformity of actions. My pushoff second looks excactly as my single and multiple turnovers.
Another reason is that my skin is very, very, very dry and if I don`t do something about it a strike becomes more difficult than a pushoff second. I can do a pushoff regardless of my skin condition.
There are also some things I cannot do with a strike.
A (one-handed) move where you pushover two cards, rotate the palm, and deal the second card face-up on the table (can't remember the name). I really can't see how you can do that with a strike second.
