Hi Wal,
It depends on your use. If you are carrying good binoculars and want a good range finder, or do you want good optics and a passable range finder?
I have the Leica Vector, Leica LRF900 (many years old now), Leupold RX IV (with compass, inclinometer), several different Bushnells, Opti-Logic and several cheaper, less usable ones.
We will not talk about the Vector, it is worth it’s weight in gold when coupled to a submeter GPS unit, of course, that is about it’s price too.
The LRF has the best optics for its small aperture but the ranging is limited in its features, but excellent at what it does. I have not tried any of the later units.
The Leupold has the most ranging features, about like the Vector, but kink of a pain in the neck to use. Better than average small aperture optics.
The Bushnells are my choice for general ranging use. Optics not with the Leupold or Leica, but the ranging, especially in the scan mode, is smooth, consistant ranging with rain, fog, near and far filters, and faster than most. Also cheaper than most others.
I have only tried one Nikon, one of the first ones and did not care for it, I have not tried any in the last few years.
