I guess I'm a boring guy. I find what I like and just keep using it (for the most part). I mostly use AAC brakes and comps. But that's more for the attachment points than the overall brake/comp performance. It's a balanced mix....in my head at least. Now, granted, I have branched out with a couple different rifles over time. But that was usually for a specific purpose/objective.
I feel that this whole subject is more of a matter of opinion and preference than anything else. But, with that being said, that's why all of us have such a diverse list of rifles.
