Yes, I know how you feel. All of my last 4 competition scopes are Nightforces and the ATACR in particular is superb. The other 3 are NXSs.
I can't truly compare to Schmidts as I don't have one (looked through plenty though) but for mechanical reliability and with the ATACR - it's glass, I'll not be going anywhere else. (And that's not to say the NXS glass is anything but good....)
