Leica rangefinders are excellent, but at the same time there expensive as hell. Nikon i personally is a good alternative to an expensive brand, they good quality and they get what needs to be done. If range isnt a worry and you aren't trying to go past 1000 yds then Nikon has all the same features. When you think of key things in rangefinders you want them to be lightweight and have many great features. I think Nikon covers all bases with a cheaper pick up.
