I'm not familiar with nightforce, but ATN makes a decent tactical scope. Illuminated reticle, changeable cams for variable calibers for the bullet drop compensator, range finder, and a nice sight picture. Only problem I've had with them is that UPS likes to break them. Of two scopes I've ordered, both came broken and had to file claims to get new ones. Other than that they seem to hold zero pretty well. I haven't had much chance to really put the bullet drop compensator through the paces. The range I go to only goes out to 300 yards, but seems to keep it in the drop range. That will of course depend heavily on the loads and grain of the ammo you're using. Commercial stuff is probably not going to drop as much.
