I can't compare to other brakes as this is the only one that I have. Also, it's hard to say as I believe the set up as a whole is what is contributing to the lower recoil. Yes, it's definitely noticeable but I think it's the Brake/Mid Length Gas System/FA BCG and ST-T2 Buffer that ALL make the difference.
What I can attribute to the Dynacomp is the fact that I'm on target after every shot. No shift up and to the right like it is with a flash hider. There's almost no muzzle rise and people at the range make comments about that every time I bring it out.
