When I was shopping for optics for an extreme long range rig I did a personal comparison between Leupold, Zeiss and NF.
To "my" eyes, which are pretty much unique to me
, Zeiss conquest was 6 times better than the VX-III and the NXS was 2 times better than the Zeiss.
Thus on the ELR rig sits the NXS.
On the LR rig sits the Zeiss.
Both scopes serve me very well.
I strongly suggest a personal comparison.
