Digital gauges are pretty accurate (they are programed by a chip). I use two, portable when inflating and TPMS..........they are within +-.5 pounds of each other. My TPMS also have tire temperature.........boy, was I surprised the first time I did extended ride in the summer.......with a cold pressure of 41-2 psi after about an hour of riding temp was up in the mid 50's range. I have 3 bikes with TPMS and they all read the same accuracy.
Being a retired aircraft tech, nitrogen has been used in aircraft tires since..............a very long time ago. Nitrogen is stable but the big thing is you don't want moisture inside a tire, moisture cause corrosion and can freeze at altitude.
