I can tell the difference between a Vortex and the Alpha tier glass. The Razor is among the best under $2500, and for the vast majority of users it’s more than enough scope for anyone. That said, when you step up to the ATACR, S&B, ZCO and Hensoldt scopes, you’re in a whole new world. For the Alpha tier scopes, it’s about deciding which specific attribute or feature you want the most. The 7-35x ATACR is a different scope than the 5-25x ATACR, and the optical quality is better.
If you’re willing to spend the money, I highly suggest you pull the trigger on the ATACR or PMII. However, be sure to figure out which reticle you really want. A simple mil hash reticle is rather unpopular these days, with most shooters opting for Xmas tree type reticles like the Mil-XT.
I would take the 7-35x ATACR over the PMII. You’re dealing with a newer scope, newer tech, and a US company.
Also, I would highly recommend that you look into Zero Compromise Optics. If you don’t know their backstory, they’re what you get when you meld NF with Kahles and make a better scope than either.
