In my experience the answer to this question is the same as the answer to that question of any gun of any caliber. The most dependable one you can buy. All things considered the knock down power and accuracy are going to be basically the same with any AKs of the same caliber.
For me I would rather a home defense shotgun with a pistol grip for home and the AK or AR for when I have to go on food runs for long distance shooting. Strap the shotgun to my back in case I need close range protection.
