The eye box on the trijicon is way bigger and brighter, the brightness and clarity of the glass in the trijicon is far better. The turrets are kinda mushy on the trijicon, and pretty dang good on the xtr. But the trij did seem to track well like the xtr. To my eyes the difference in glass was extreme. But the difference in turrets is also kind of huge the other way also. But to me id rather be able to see what im shooting at then be able to dial to it and not see it, if that makes sense.
