They're quiet, fast, and apparently accurate. As for myself, no I haven't played a game with one yet but I'd like to and probably will this weekend. I'll let you know at that time. They seem to offer a lot in their design from both their inherent characteristics and their mega potential from upgrades. Just a simple sleeve on the bolt for example lowers pressure a lot...supposedly a bolt assembly from Aardvark that someone told me about takes the pressure down even more and still improves efficiency. This I must see for myself. I do like the trigger a good bit, and would like to test out a few different trigger styles to see just how good it can really be.
