I don't have a lot of experience with rangefinders, it isn't something I replace very often. If money was no object I'd buy Leica Geovids, but the Lecia Rangemaster CRF is probably be my next purchase. The bane of my rangefinders is Pronghorn, I've used a few different brands over the years and Leica are the only ones I've be around that'll give me a reading on pronghorn.
I've had Leupold, Nikon, and Bushnell variations of range finders over the last 20 years. They would only work to maybe 300 yards, usually less on pronghorn. Leica would easily double that and more in most cases. I haven't been around a Swarovski, Zeiss, Vortex, or Sig RF to give an opinion of them.
I do think if you can afford them RF Binoculars are the way to go. The added weight of the binoculars makes it easier to steady and give better readings. You also don't have to switch between optics, which is a winner IMO.
