I own both mentioned STI pistols. The edge from brazos has a better trigger, the pistol was perfectly sighted in, double taps are amazingly close grouped. The DVC has a better grip, less felt recoil, and less movement in the front sight during follow up shots.
Both have pros and cons, personally I prefer the DVC but with spring tuning and a grip change it would probably be a wash.
That being said they are around the same cost minus any upgrades.
