I have tried them all and the Leica is in my opinion the best. With that being said I own the Leupold with angle compensation. It works well and even has internal adjustments for the bullet type and speed you are using. Same thing for the bow. It is almost to damn smart. The only beef I have with it is that it wont range a black target. I hunt a lot of hogs and they are usually black. So I point it at their feet.
