I have never shot one, but from what I have read and seen, you are correct. It is a pretty reliable piece of work at a real bargain price point. 9 mil or 45 carbine is a great home defense choice.
I know the latest American Rifleman had an article by their tac expert saying an AR was his home defense choice, and he had many valid reasons. For me, the main negative of an AR is likely ear damage from firing it inside the house with no ear protection. I'm not really sure how big a threat that is, but he admitted it is very loud inside a house.
