Yeah, after researching and working with the Storm a bit I'm pretty excited about it. I think it offers a lot of options.
The Pistol Caliber Carbine is just a janitor in the land of the rifle, but it's King in the realm of the pistol. Other than carrying covertly, anything you can do with a pistol you can do easier with a PCC.
It's a niche tool, and isn't the best choice in some arenas, but in its niche I think it's excellent.
Personally I think it's the best tool for home defense, as I note in the article. Love my rifles, but I've got no desire to touch off a round in my home. I like my hearing, and though I have ear pro at my bedside there's no guarantee I'll have it on...and I like my family to be able to hear if shots are fired as well.
