Since no one else has replied, I will give you my opinion based on my admittedly limited experience.
I have owned a Steiner C35 (Chinesium core) and currently own a NOX35.
I have time behind a Guide Sensmart and an Iray RH50R that are owned by friends.
Like anything else in the optics world, best depends on your priorities.
My NOX is mounted on a 14.5” AR pattern rifle in 5.56mm. Its intended use is 2-300 yds. max.
I wanted something small and light with an emphasis on image quality and sensitivity.
I had no interest in multiple color palettes, a range finder or onboard recording.
It weighs less than the LPVO that it replaced.
IQ is subjective in any optic, whether it’s a thermal or a day optic.
I much prefer the image from my NOX to that of any of the sights with Chinese cores that I have used.
My friend who owns the RH50R is happy with it. He wanted the features and was OK with the trade off with IQ and sensitivity.
Although the Nvision stuff has been out for a few years, I think that when it comes down to being able to see and identify things in the dark, it’s still tough to beat without spending a lot more money.
