Just my .02. I'd go with AA for a several reasons. It's in stock, and I hate waiting. It's got a tighter twist, so possibly better accuracy potential over a range of bullet weights. It's less expensive, so I can buy other cool parts I need. It's fluted, and everyone likes fluted barrels. It's the original chamber, made by the original. But that's just my .02.
