Miguel,
 
    I think digital levels are less accurate than a bubble, especially when it is cold.
They depend on a “swinging pendulum disc” inside, and those can stick in freezing temperatures. If you check, sometimes you need to give them a tap, to overcome this stiction.    But they are adequate for most cases.
