I have tried both for my M&P Shield. The granular grip is a more positive grip but the problem is it is like velcro against cotton. My t-shirt would snag on the granular grip when I would draw my pistol. The rubber grip isn't quite as nice in the hand but no snagging on t-shirt when drawing. So I guess the moral of the story is there is a trade-off between the grips. I figured what good is a really nice grip if you can't get the pistol out of the holster? The granular grip is excellent if you want it for a range gun but not so good for a carry gun.
