The louder they are the better they work
This seems to be true. I have also found that the angle of the ports have a lot to do with reduction of recoil. I have a MPA Cowl induction brake that reduces a large majority of the recoil. Angled ports throw the noise/gas back at an angle. I also have a Badger Thruster brake with ports cut on the side with no angle. There is a huge difference in recoil b/t it and the MPA.
I only use brakes at the range with doubled-up hearing protection. I won't use them hunting due to the increase in noise. I hate cleaning brakes as well.
If looking at a brake today (for the range), it would be Eric Cortina's tuner brake.
