I'm with Scott on this one OP.
There is no "one" magical, BEST when it comes to such a broad platform as the AR.
Do you want a mid to longe range gun? You will want a longer barrel (20",22"), heavier optics and might not even want to go with the standard 5.56/.223 caliber
Do you want a door kicking, room clearing bullet hose? You will want a short barreled rifle (SBR), maybe in the 12.5" barrel category, with a collapsible stock and heads up optics.
Do you want a short, street to street, urban sweeping application? You might want a 14" or 16" barrel with a low power optic (1X-4X) that still offers some decent knockdown power and reliability.
If you are looking to just own the most drool worthy stick out there that will turn all the heads at the range you will probably want to go with more of a dedicated true custom, and not a production run, gun.
I am not a fan of the man, but the work that comes out of his facility has always been top shelf and while I have only ever shot two AR's with his stamp, both were incrediably well made, accurate and beautiful.
