Yeah, I'm aware. I want the one with the best optical quality. Everything else is secondary.

I have owned all three of the above, and it's hard to tell which one had the best glass as all three were superb in that department.
So in that respect you may want to actually want to look at the secondary aspect of each of those optics. I honestly couldn't tell much difference in their optical quality.
I guess if I were to nitpick I'm going to say the eye box on the Vortex, and Trijicon were the most forgiving at 1x. Even with that all three are really close.
You also may want to take into consideration that everybody's eyes are going to see through these optics a little differently and you're going to get some very different answers.
Hopefully a couple of our optics gurus will post in here shortly and be able to really give you the more scientific details. Still really hard to judge unless you've actually looked through them yourself.
