I own both and both are great scopes. IMO you get a bit more for your money with the Razor. I plan to purchase both again in the future. My determination is based on whether I want FFP or not for rifle it will call home.
Comparison based on my experience:
- Zero stop - standard with Razor - both work as designed.
- 35mm tube w/ Razor vs 30mm w/ NXS, though I get all the adjustment I ever need from the NXS
- Optics are very similar in quality on both scopes at least to this part-time photographer's eyes. To me, the Razor sometimes has the edge here.
- Much prefer the numbering and graduations on the Razor reticle
- High speed turrets std w/ razor, although NF gives you more MOA per turn if you do upgrade
- tracking is excellent on both scopes
- Both could be run over with a D5 and still function just fine, though the NXS has the record to prove it. Razor actually feels more "beefy" to me.
- Both are heavy enough to substantially reduce recoil !
- Razor has better thought out engineering, for example, the illumination dial has an off-position between every level of adjustment. You are always one click away from turning off the illumination. Scope was obviously designed by a "shooter".
- Razor comes with scope level and Flashkill - nice!
- 35mm rings are hard to find if you need a high mount. I ran in to this on my FAR Titan. Medium Vortex rings should be fine for most bolt action rifles.
- And, of course, the FFP vs SFP question has to be answered for your particular application. Sometimes, I want SFP and so the nod goes to NF on this occasion. The Razor reticle does get a little small at low power, but is still usable.
- I have not had to use NF customer service. I understand it is excellent. I have used Votex CS and it is phenomenal. When I first bought my Razor, it did not have the eyebox upgrade that Vortex just came out with. I called them and they had me send it in for a free upgrade. They could not have been any friendlier on the phone. I mailed (std snail mail) the scope on a Fri from upstate NY to Vortex in Wisconsin. I received the scope back on the following Wed....I'll leave the math as an exercise . Suffice it to say, that someone probably stayed late to turn my scope around when I had already assured them I was in no particular hurry. That's the kind of service that made this country great not so long ago.
