Leicas and Swarovskis are awfully nice.
However, I'm pretty happy with my Nikon. I have a 400 meter one, so it's not as long-range as you want, but they do make them also.
Mine is good, as advertised, to 437 yards on anything I can point it at, even foliage and power poles. Bright sunlight shining directly on the object limits this to a bit over 300 yards. The thing is tiny, and has nice optics. The price was great.
Nikon doesn't rate their units "12000 yards on reflective objects, 50 yards on deer" or some such thing that I've seen on others. They rate them at a certain distance, and that's it. From what I've seen, this is accurate.
I have no particular need for anything past 400 yards, but if I do, I'll probably get getting another Nikon. I think the quality and value are excellent.
While I've used Swarovski binocs and I could see paying for them if I needed binocs a lot. The optics are incredible. However, Nikon isn't a slouch when it comes to optics. And you use binoculars in a much different way. I can't see glassing for faraway or well-camouflaged game with a pocket rangefinder.
