Hmmm... I would have to respectfully disagree.... at least about the part of not getting a brake. I've shot Smith, JP, and another comp I think was made by Krebs, and they make a big difference when shooting offhand, like in a 3-gun match.
For me, it's not about recoil, but controlling muzzle flip. When you're running a short to medium length stage, or one with only partial targets visible, that little bit of flip costs you time and points because it takes you off target. With a muzzle brake, you stay on target and reduce split times. I can see my hits on long range steel and don't have to wait on the RO to call the hit or listen for the bullet to strike the plate.
