I have no experience with the burris. Had the furys for a couple years. The glass is on par with their viper line. Also had to warranty them due to eyecups falling apart. The range when tested showed greater than 10% error so they were replaced. Wasnt hard on them they were always in a harness. Needless to say I wasn't impressed. Leica has a set at 2k and they are real nice.
I've had a set of Fury 5000ABs for almost 3 years now, no issues. Glass is good (not Swaros, or UHDs, obviously) and the laser in mine is fast and accurate (have compared to Sigs, Steiners, etc). I think they're great value for the money.
