I have lots of Leupold scopes, some old fix some variable in the vari x3i some vari x II and III and even a rifleman and to be honest even the rifle man is a good scope or at least for hunting purposes! There is a lot of stuff on paper that looks impressive that in real life is actually marginal/not noticeable! But like other said that is just my opinion and observation! That said I never set eyes through a night force or Swarovski Leica or high end Zeiss…
I was interested in comparing the Leupolds to Nightforce, Swarovski, Zeiss and Kahles.
I spent some time at the range with my mentor working on several rifles for load development for customers at the LGS, and performing scope assessments of the various scopes mentioned (our own unscientific field test). Scopes used for comparison were of the same configuration (1" tubes with same sized objective lenses - 50mm, set at same magnification levels (7x) for best apples-to-apples comparisons. After a few range sessions lasting hours apiece and covering bright sunny conditions, to cloudy overcast and first and last light scenarios, we found that the Kahles had the best low light resolutions and definition, and that the Swarovskis and Zeiss were very comparable and gave great performance. Just did not give as good as the Kahles. Nightforce and Leupold were definitely not in the same class, but still performed well overall. But it was clear that for twice the price, you were getting the same low light resolution and definition between these two, but not as good as the higher end glass.
For me, I ended up buying 2 Leupolds (VX-L's w/ 50mm objectives) for same price as one Nightforce after this, as I could not afford 2 Kahles or Swarovskis at that time.
Since then, I have purchased Kahles, Swarovski (Z3 and 5) and a Schmidt & Bender. But I still own several Leupold VX-III and VX-3 scopes, and a VX-5HD. All great scopes that have given me years of solid, dependable performance. I have now upgraded most to those w/ B&C reticles, except for the 2, 1.5-5 scopes.
