I have one on my AR pistol. I can't tell you how it compares to anything else since it's the only thing I have ever had on that particular gun. I will say that after reading stories about other people's 7.5-inch barreled guns that I was really surprised how tame this one seems to be, but I don't know if that's just me or the Levang actually helps. Either way I am sticking with it.
By the way, here's a couple of shots from a video I made..
