That depends on you. I tend to prefer the standard stock design because it handles a bit faster for me, but that might also be a reflection of decades of using such stocks on, mostly, Remmy 870's. I have two Benellis...a pre and a post ban, and have a pistol grip mounted on the preban gun. I will admit that for "game" shooting, the pistol grip does let me cut my times down a bit, and it will also allow one handed operation in a pinch, although I am not so sure if the gun would function as it should with one hand...never tried it and I don't want to!
My biggest complaint with both stocks is their length...too long. I am not ready to spend a bunch of bucks to have either professionally cut down, but one of these days me and Mr. Jack Daniels just may decide to try it ourselves!
