I have had the razors and XTR ii 1-8.
Glass is clearer on the razor, especially at 6x. I feel like the XTR gets a little cloudy from about 5.5 to 8.
FOV is better in the razor.
Reticle in the XTR is far superior in my opinion, and I don't usually like FFP.
Illumination is much better on the Razor.
XTR can be had for much cheaper on the used market.
I only have an XTR ii left, let all my razors go. Like stated above kind of different scopes, especially given the SFP vs FFP.
