Why apples to oranges? I am interested in mostly same specs (8x42 heavy duty body or at least not easily breakable, shock resistant). I am wondering why all the 3 costs 500-1500$ more but doesn't offer any lifetime warranty and from other forums and reviews if something happens or breaks with Leica or Swarovski it's a trouble to get it fixed.....Lol but agree with jgraider on both points. Also there is quite a big spread in price point between the Vortex and NL Pures. So you’re comparing apples to oranges. All the more reason to check them out yourself and hopefully side by side. You may find out there’s not enough difference to your eyes to justify spending double. Or just the opposite. Good luck.
