I had the total opposite experience multiple times with my 4-32 NX8, sold it because the low light was so terrible in hunting conditions. I have several scopes that I use for hunting and all of them are Swarovski. They are night and day brighter at first light and last light while hunting than either an ATACR or NX8.
Didn't have any problems otherwise with the NX8 and really liked it, as it does check a lot of boxes. Better glass and turrets than the NXS and a few ounces lighter. Most of my time in the woods is hunting whitetails at first and last light and I was repeatedly having problems with not being able to see through my scope well enough to shoot with the NX8, when my binos, naked eye and rangefinder were all brighter...
