I'm not going to bash any other brands here. I'll just say that I'd highly recommend one of those two I listed more than any other popular piston gun out there.
That said, I'd rather have a nice BCM, KAC, Daniel Defense, Noveske, Larue Tactical, Colt, etc, etc.. Shit, if you got the cash, get a Larue OBR. That'd be a great change for you and would be plenty "different" from your regular 5.56mm ARs.
That's all I got for ya, man. Good luck!;)
