A lot of the spec ops guys I know prefer the old M-14 to either. They generally like the old 1911 better than the Beretta.
The AK family weapons are generally fine utility style weapons, cheap, reliable, and low maintenance. Not real accurate, especially at longer ranges, and not real powerful. They don't do anything really great, but they do most things fairly well. All in all a good weapon, and when you consider factors outside of how well the weapon does its job, it ranks up there among the top 10 of all time.
