IMHO there is only one. Leica CRF 1200.

I've ranged deer sized animals at 1159 yards. It does one thing, tell you how far your target it. It doesn't compensate, fill the screen with B/S. It just throws up a number, bam. And does it better than any other. And has a 7X magnification, and is clear as a bell, as good as binoculars.

The End.
