Surface area of the ports and there direction are the two main deciding factors in a brakes efficiency.
If your looking at 2 brakes side by side both with 21 holes 5/16 in diameter the larger the outside diameter the more efficient the brake will be.
That said if you had two brakes the same length and diameter both with 21 holes but one has 1/4 inch holes and the other has 5/16 inch holes the brake with the larger hole diameter would be more efficient if all else was equal.
Any forward facing holes detract efficiency but help to reduce noise.
Any rearward facing holes aid in recoil reduction.
Expansion chambers inside of a brake increase efficiency all else being equal.
To compare two brakes side by side is very tough unless they are mounted on the gun itself and you get to pick which one you prefer.
Brakes get less efficient with distance so just adding more holes on a longer brake in order to get more surface area for the escaping gases to impinge against doesn't guarantee more efficiency because the gas slows down very quickly meaning those forward holes do less.
The clamshell brakes generally work the best because the rearmost ports are huge and reaward facing. The downside is they are extremely loud and move the concussion rearward closer to the Shooter.
Last Sunday I was helping a 338 Lapua Improved Shooter who was squadded next to a 510 DTC Shooter and every time that cannon went off it got your attention but not from the noise it was the shockwave moving through your body.
