The thing about gliding SideB was that he already had that mechanic in by holding jump after a midair jump, so to me it was a waste of time to move a special mechanic to a Special attack slot. The UpB has kill potential...that is the only good I can give it. Pit doesn't need anymore potential to kill upwards on the ground, but I guess it's a surprise move in midair. PM only did well with a few characters, in my opinion, and Pit isn't one of them. Then again, I don't like the feel of PM as a whole, so I accept the possibility that I am biased.
