Late reply so you probably won't see this, but how so? They are extremely reliable, extremely common (parts availability top notch), ammo availability is second only to a 9mm pistol, it's extremely easy to shoot accurately, and the ergonomics are the best out there.

Obviously the ergonomics argument is a little subjective, but I've trained with several rifles, and everyone performed best with an AR platform. Instructors say this is very common.

That being said, this line of conversation reminds me of the 9mm / .40 / .45 debate. Maybe relevant in 1990, but gap between everything is so narrow now it's a historical argument.
