I tried the Sig Kilo 3k next to the Vortex Fury 5k AB. I felt the Vortex had better glass but not by much. I later bought the Zeiss Victory RF. The glass is night and day different. The Zeiss returns almost identical dope instantaneously. The Vortex takes a bit to return the dope. Paired to the Kestrel or the Tactix, though, it provides immediate dope on those devices.
I use the Zeiss for hunting and the Vortex for competition. You can't beat the warranty for when, not if, the wind blows over the tripod and they hit the ground at a high rate of speed.
