I can't even think about NX items unless what I'm buying will be perm. I've tried a handful of 1HKO snipers and so far my favorite is the L115A3. It has better accuracy and a better scope than the L9 family. I've been rage kicked more times with L 11 than any other SR, so that speaks volumes to me in terms of how deadly it is (in my hands).

I've tried the GP variant L115A2, and honestly it doesn't feel the same as the NX version. I've owned the TPG-1 Pro for 90 days (from an event) and to me they're very similar. I had the L9 Arctic for a week or so, I felt it was so-so. It was lighter, shot a bit faster, but overall I didn't care for it.

Your best bet is to walk into sniper only rooms and pick guns off the floor and find one you like. That's what I did when trying to figure out which one to buy perm.
