I've used RF's from several different brands including Leica, Leupold, Swaro, Sig, and Vortex. I've had trouble with all of them, mainly losiing their display or RF being jacked up except for the Vortex as I've only had the Fury AB's for about a year and a half. IMHO, since they're all Chinese electronics (no matter the brand), I'd get the one with the best warranty as you'll likely need it at some point. If you don't consider yourself lucky.
