IMO, the choices for whatever you use for HD are personal. Your family situation (kids in the house?), home layout (all bedrooms together? at opposite ends of the house?), location of your house (in a subdivision? out in the country with neighbors over a half mile away?) have an impact on your choice. But the number one would be what you're most effective shooting. If you shoot a 4" revolver well and are comfortable with it, go that way. If you're more comfortable with a shotgun, go that way. But no matter what you elect to use, first and foremost you need to be well drilled in its use. Just imagine being awakened at 2 a.m., being half asleep and the alarm going off and having to be effective in operating a firearm and putting shots on target. If you're not comfortable enough to be able to operate on muscle memory and instinct, you need more practice. And given how we're all different in what we prefer and why, as well as our circumstances, I don't think there's any 'one size fits all' best HD weapon out there.

The article also talks about the advantage of a rifle being shorter to maneuver around furniture and corners in the house, then discusses the advantage of being able to mount a scope. I can't think of a scenario where I'd use a scope for a shot at an 'inside the house' distance. At those distances, a shotgun using bird shot is devestating. But, if you have kids in the house I'd maybe re-think the shotgun. I don't, so I haven't thought that through. If I lived in the country where the dogs would wake me up before the BGs got within shotgun range of the house, I'd likely opt for a scoped rifle.
