In theory nitrogen may bleed out a tiny bit more slowly than good old air but most will not ever notice the difference. The one significant, potential advantage of a nitrogen fill is being moisture free. If a shop is properly maintaining their compressed air system, moisture should not be a problem. But I've seen air systems with visible sprays of moisture coming out. That wetness is probably not so good in the long term for TPMS sensors and will make pressure swings with temperature a bit wider.

Bottom line filling with clean, dry air is perfectly fine.
