The shotguns advantage is versatility. Swap the 18.5" barrel slug / buckshot barrel for a 28 mod. Choke one and shoot birds. If the goal is home defense they work well if you have only one firearm.
Personally I prefer a handgun for inside use due to maneuverability and difficulty getting disarmed. Outside I would chose a carbine, greater accuracy.
The shotgun can do a good job at both with few limitations
