That's very debatable. Under stress, people are much more accurate with long guns. On the other hand, they have terrible weapons retention properties, as I've e.g. demonstrated to my taller and fitter nephew about the time he graduated from high school, quickly ripping my shotgun out of his grasp by gaining a longer lever arm by grasping it outside his grasp. And without injuring him, but an adversary wouldn't be as gentle, especially after gaining the weapon. This is what the all too common recommendation of a shotgun for home defense hinges on. And in more than a few states that highly restrict handgun ownership, a shotgun is much more practical, which is what I did when I lived in Massachusetts, the first gun I ever purchased.
