As far as Unique's relative dirtiness goes, I used to use it exclusively, and I didn't think it was too bad then, but then I tried VV N320, and N320 is just a whole other world. I went from cleaning after every or every other range trip/match to cleaning more like every 1500-2500 rounds. Part of that was a a realization that it just wasn't important to have the gun be spotless, but it's also that Unique *is* significantly dirtier than N320.
