I have 2 rangefinders: a Leica LRF 1200 (about 10 years old) that I need to change batteries periodically and a spanking new Leupold 1000i TBR with DNA (all the bells and whistles). I bought the Leica for rifle hunting and it has always worked. Not small or angle-compensating or won't do continuous measuring, but does an excellant job of ranging, especially the non-reflective targets. Was the best one on the market at the time, and frankly, probably better than a lot on the market now.
The Leupold was purchased for archery applications. I looked seriously at both the Leupold and the Vortex. Both would be a quality product and I am a Leupold person before Vortex so that is primarily why I chose the Leupold. I hate having to read instructions and having to make all the adjustments that you need to in order to make the angle compensation work (but is a necessary evil). Once you are set up, just point and press and you get a quick answer. Time will tell on this purchase but it is small and fun to play with.
I had them both out one day (I had one and my son had one) and we both ranged a tree about 800 yards away. One said 800 and the other said 790. I presume that we were pointing in the same general area so I would say that the accuracy was relatively the same.
Angle compensating for rifles are great, but if you use more than one rifle, you will potentially change the setup in the rangefinder for the best accuracy.
