You should be chasing for spec values but they don't exist and if you wanted to know what "better spec" values are there isn't a way to know which unit is desirable over another.
Most retailers will post this info as they resell NVDs, first come first serve, and depending on their grading scale of high, mid, low tier it may differ from retailers. If a retailer offers a “ready to ship” fully built units they won't list the spec values. Hand select isn't an option from retailers that will try to match to your spec requirements.

SNR: signal to noise ratio, the amount of signal the tube can make compared to the noise
EBI: equivalent background information, how much false image appears in the screen through which the actual image has to show, sort of a noise floor of sorts
Halo: How big the circle of bloom is around lights
Photocathode Sensitivity: How sensitive the photocathode is
LP Resolution: Line pair res of the center of the image as measure against a standardized chart

If one spec is shit it doesn't negate the rest, if you have a halo of 2.0 it kinda fucks on an EBI of 0.20 if you want to do any kind of shooting and it's all a tryhard game

The numbers to meet or beat are
EBI over 1, over 0.6 is ok, 0.1 is shit
Halo over 1, anything under 0.7 is gay
SNR, under 25 good, anything over 30 is terrible
Photocathode, 1900+ is pretty horrendous, 2500+ is irredeemable
Resolution of 64+ is undesirable, 72+ is 80s tier

this was my intention
