Given how less durable Cerakote finishes are compared to hard anodized (and I say this as a happy owner of FDE AR), Just take the money you'd spend on a "professionally distressed" finish and spend it on a carbine class or two and you'll get a "battleworn" look and gain some proficiency with your AR in the process.
I don't mind the look of honest wear on a firearm. Of course to me, that's totally different than having idiot marks...
