My friend has an older NF. I have a3x15 swfa. While hunting bears one evening we put the rifles side by side and watched until dark. To both of us there was little difference to the point where we couldn't see any more. They both worked fine. I am not sure if NF has changed or improved their glass on newer scopes. Leupold has very good glass but their quality is not very good right now in terms of returning to, or retaining zero. As has been pointed out on many of these optic threads, the scope is an aiming device and reliability should be the main concern. If you are shooting really late, or early,get a scope with ban illuminated reticle. Both NF, and SWFA have them.
