Digital thermostats are WAY more accurate, and react a lot faster than analog thermostats. Old analog thermostats also need to be calibrated semi-regularly, as even bumping against it wrong can throw off the metal pieces inside that are used to react to the temperature in the room.
I don't know what you're referring to when you say that they "fuck up" all the time, but there isn't really any widespread issue with the accuracy or reliability of a digital thermostat, and certainly nothing related to the mechanics of actually reading the temperature of your home. Hell, they can even account for being in direct sunlight by subtracting the warmth they gain from the light. Analog thermostats can not.

What do you mean when you say analog? Mine doesn’t look like this but looks like an analog clock. It’s connected to a gas furnace in the floor. Is this the same thing? I’m just curious.
