First, what are you gonna be using it for ?
I believe I would buy a Leupold VX III or Mark 4 before the ATN.
I assume from your question, that you personally have not held one in your hands ???
It is important to judge using your own eyes... Everyone will tell you their own opinion.
It is kinda like Ford guys hate Dodge and Gmc and vice-versa.
use and find what you like... Myself included are bias towards one scope or another based on personal experience.
