I will leave that one to the experts.wait...Theres got to be a differenece which side the leading edge is on (Fat Side) because right now you are probably turning it with the thin side leading which is probably really inneficent.
I'm sure someone will chime in soon about the REAL difference.
The blunt edge of a prop is always the leading edge. Standard puller props spin counterclockwise, and pusher props spin clockwise. I dont have any pusher props to compare to, but I have seen them. The leading edge is on the opposite side of the blade. The blunt edge of a puller would be the sharp edge of a pusher.
