The current day digital sensors are a lot more reliable. I have multiple cheap digital thermometer etc gadgets and they read the same temperature to within 0.1 C, humidity to ~0.5%, and so on.

The source is analog only in the sense that physics is "analog" until you get to Planck scale or to quantum phenomena.

I also have some digital thermometers, and personally don't have any preference digital vs analog in them. For home use, +/- one degree or percentage of humidity don't really make a difference. As for reliability I don't think you can beat analog, which will last for decades without changing a battery.
