My first semi custom rifle came from MOA rifles with the nightforce shv 4.5-14 x 56 already mounted. My next one had an NXS on it. I felt that, at least for my eyes, the SHV was brighter and clearer. I sold the NXS to one of my shooting buddies and replaced it with the 4.5-14 x 50 F1 SHV. It's not quite as bright as the 56mm objective, but I still feel the glass is plenty good. The turrets are definitely more solid and robust on the NXS, but I have never had any issues with the turrets on either SHV. Both are very precise and adjustments are right where they should be. If I were considering spending the extra $$, I would consider the NX8 2.5-20. I recently put one of these on a 33 nosler and am very happy with it. You get the low end magnification for your thick woods hunting, yet maintain the ability to use it for long range to stretch out your potential on that '06.
