> I would still encourage use of a shotgun loaded with buckshot for home defense

I don't really have a dog in this fight, but one thing I've heard from "gun enthusiast" family members is that this is fine if you're imagining an "ideal scenario" of being barricaded in your room waiting for the cops to show up, but it's worth considering what can go wrong - compared to a shotgun, an AR is much easier to operate with one arm (if you just woke up and one is asleep, or you were involved in a struggle that disabled one, or whatever); much less recoil (could be an issue if smaller family members need to use it); faster rate of fire and more rounds available before reloading (in case you miss or there are multiple attackers).
