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

Some reputable retailers:

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 negates 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 balance game

The numbers to meet or beat are
EBI under 1, preferably under 0.6 being great, 0.1 is gucci
Halo under 1, anything under 0.7 is awesome
SNR, over 25 anything over 30 is gucci
Photocathode, 1900+ is pretty great, 2500+ is stellar
Resolution of 64+ is good, 72+ is gucci
