Does anyone have experience with both the the QDC brake and flash hider muzzle devices? I'm thinking about putting one of two on a 12.5 inch piston upper to use with a CRS3. Which would you recommend and why?

Assume you're talking 5.56? If yes, I don't think the 5.56 version of the 2-port brake has been released yet (but it is shown on KAC's website).

According to KAC, the brake is a bit louder with the can because of how the gas channels are routed. You get the benefit of the "sacrificial" baffle in the brake and then muzzle climb reduction unsuppressed. Your firing cadence and performance priorities will help to weight those factors accordingly.
