Not sure, didn't check them side by side ... this one is incredible in my opinion, but my ATACR is really nice too, so there is no way for me to answer the question.
Honestly, I am gonna check this with the FinnAccuracy Optical Standard test, but I really think questions about glass are BS. Ya, I know people obsess over glass, but really, it's so subjective it's silly for me to compare it. Two weeks later some guy who just got lasik with 20/15 eyes is gonna bitch he can see something in one scope he doesn't see in the other, but for me, I'm like whatever, I can't see it in either scope, I don't have 20/15 vision.
Without using a standard like the one FinnAccuracy provided where you can provide a number, I mean, come on, I took a through the scope picture above. I said my sight picture was better in person, what more can I say that would tell anyone anything beyond what Frank can see ? You can see what the camera took.
It's the internet, I can't show you what I see ... You want to ask about glass, line 10 people up and have them all look without any of them giving an opinion until after they have all written their opinion down, then average the score. That way you have a half-assed estimation of the "glass" ... me I want to know how it adjusts.
