I wrote this 2 days ago in response to a PM question - but it seems relevant to this thread as well.
I had made the statement that I liked the ATACR 1-8x dmx better than the NX8 1-8x dmx but not $1000 better, and my PM mate responded with ...
What is it you prefer about the ATACR?
I can usually answer such questions very objectively.
I do like the dmx reticle better than all the other lpvo reticles i've seen due to the tiny center dot FOR A DMR.
So thats a key reason why I like the atacr over the vo 1-10x. That said, for fast shooting and UKD targets I like the BDC/WD (wind dot) reticle - which they call a "moa" reticle though inside 650yds its a BDC reticle with wind dots.
(i like wind dots which is why I like the t3. There are only 3 reticles i know of with wind dots and I have 2 of them)
But mainly i like the atacr because of what my brain sees when i look thru it.
My brain some how sees both the target and the reticle better thru the atacr than the VO.
The VO reticle is grey i guess to suppress it and make the target easier to see. So thats why i can see the reticle better with the atacr. But why can I see the target better ?
IDK.
The exit pupil is larger on the atacr so thats my guess.
And the exit pupil is smaller on the nx8 than on the vo which is smaller than the atacr.
For a DEG (Do every thing gun), like a 556(14.5) with a great lvpo I'd want an atacr if my life depended on it, but for mk18 which is more likely to be a cqb gun, the nx8 is more than enuff, dont need.to spend the extra $1000.
I already have 2 atacrs that might be enuff.
Well that was a looong answer to your question, but I wanted to be complete !

Back to present ... so net/net for me it isn't a linear question/answer.
For higher accuracy, I prefer the dmx reticle in the atacr and nx8 1-8s ... but for fast shooting I prefer the BDC/WD (aka "moa") reticle in the VO 1-10x. I have 2 ATACR dmx, 1 VO 1-10x BDC/WD and 1 NX8 1-8x dmx.
The atacr wins on exit pupil, ability to see the reticle and ability to see the target.
The dmx reticle wins on accuracy
The BDC/WD ("moa") reticle wins for fast shooting
