I won't argue against Larue making quality products, but you do pay a bit of a premium, and their QD mounts aren't very Q. In their favor, the 34mm mount I had worked great with inserts so I could run my 30mm scope in it. However, when switching it from bolt action top rail to AR top rail, it was a royal pain in the ass to adjust, so I got rid of it in favor of an ADM mount.
The Larue requires that you have that damn little wrench to adjust the doojigger when you put it on a different platform. The ADM lets you turn the adjusting screw with a fingernail.
For me, the ADM mount configuration is a much better option if you're actually going to be swapping your mount back and forth.
