The vortex works very well as a flash suppressor, not sure why you need a brake on a 223
For brake I'd recommend PWS FSC556, or lesser extent Vltor VC-1.

I've just ordered the PWS Triad from Questar so I'll see how it works compare to the 2 above.

I'd love to see some side/by side comparison when you get the PWS. I've been toying with changing out the A2 flash hider on my 10.5 AR, but have no idea where I'd like to go lol.
I vote for Vortex(#2)...but like you said, #1 may be useful (to pound meat?)
This Dlask A6 is the best muzzle brake I've tried for the AR.
