I own a CR-2A and I love it, but it's certainly not the best in the Nak line. I would suspect most would agree that honor goes to the Dragon, although they can be absolute beasts to keep running properly. After that, no clue. I've run across quite a few Naks, some are great, some seem a bit misguided in their design...but I don't think I'd turn down any of them in proper working order.
