I've got some trigger-time with the AK. I think it is a sensible choice for a defense rifle.
For the average new shooter, I believe the AR-15 is easier to handle and make hits with. Mainly due to better sights, better trigger, and lower recoil.
To me, the strongest part of the article is ammo price/availability. I've added a few AR uppers in 7.62x39 for that reason. Wouldn't mind having an AK though, to go with that ammo.
