Brakes work differently for different rifles, different ammo and different shooting styles. No one unit is gonna be the best at anything. I say you buy one of each and let us know what works out best for you.
My personal opinion (I have not tested them all out)
best maximum recoil mitigation - Surefire MB556
best compensation - Ares Armor Effin-A
lookup my thread history I did a totally informal review of a few rifles with different brakes/comps
