Patrick Kelly did a series on comps and photographed the tracking with a laser. Google it.
I found this with google.

I've been considering the compensator Jerry Miculek uses and designed with DPMS. I don't have any experience with it but reviews are favorable and it's nicely priced.
In another lifetime, I spent almost a year of my free time researching a developing muzzle brakes for AR-15 pattern rifles. I quickly found out that to design them properly you really had to have an engineering degree and VERY specific specialization. Which I didn’t. Just finding quality information on the subject was highly difficult, and most of the stuff I found was decades old. I once tried to calculate by hand the efficiency of a brake I “designed” using a formula I found in a dusty text. I got stuck 3 pages into the calculations.
Anyway, the best of them are designed to be barrel length specific. From my research, as I remember it, three baffles are the max on .223/5.56 rifles before you start getting deminishing returns on their effectiveness. Some of them work quite well, some not so much, but in general the large port, side baffle designes worked best.
My current AR, which I hardly shoot anymore (I blame IPSC), wears just a plain old A2. These days, I would probably only use a brake if I was competing. They do work to keep the gun flat during fast strings of fire, but they are obnoxiously loud and disorienting the movement you shoot them near barriers, or inside any semi enclosed structure. Shooting on a line in a class beside folks with brakes is horrible, and going prone, or urban prone, kicks up a horrific amount of dust. IMO when using brakes outside of competition, the juice is not worth the squeeze.
