Ultimately, it is the 1x performance and form factor that made me choose the NX8 over the ATACR and its slightly better eyebox and superior (I'd say 10% or so) optical properties otherwise.
The NX8 is pretty much a true 1x in Zone 1-2. The ATACR is very flat, but never achieves unity for me, once diopters are all correctly set. The true unity of the NX8 > The flatness of the ATACR, to my eyes/brain for rapid 1x use with the bright lit reticle being the center focus.
