So, I've been running the XTR III 5.5-30X56 for a little while now for a review I was working on and along the way I'd been comparing it to my NF 5-25 ATACR. Unfortunately, I don't have a Vortex Gen II to compare it to but compared to the NF, the two are really very close. Doing a side by side comparison of the two looking at the same objects, the NF had a little better IQ with less CA and maybe slightly better resolution. That being said, the Burris was no slouch so when I say the NF had slightly better IQ I mean that if the NF was a 10, the Burris would be a 8.5-9. I did notice that when the scopes were set to the same magnification it seemed like the Burris had a slightly better eye box with a similar field of view.
I've tested the tracking on both scopes and both scopes tracked perfectly, nothing really earth shattering to report there. I like the feel of the elevation knob better on the NF but I think that's because I'm used to it, the Burris elevation knob is still very audible and tactile, not mushy at all. Oddly enough, the Burris has better feel on the windage knob compared to the NF. Parallax is equal between them in so far as feel and function, but I'd say the numbers on the Burris are closer to being accurate, at least as far as I could unscientifically test at 50, 100, 300 and closer out to infinity.
All in all I think the Burris is a solid option in the sub-$2000 category considering that it's more than a $1,000 cheaper than the NF, lighter, and the same length while having an extra 5X on the top end. Again, I don't have a Gen II Razor to compare this too but I imagine it'd compare favorably there as well while also being much lighter. I've good luck with Burris optics in the past so I have every confidence in this scope.
