Although they're easier to read, digital readouts don't do anything critical that the dial readouts won't do, unless you're getting into fancy stuff like averaging multiple measurements and calculating standard deviation, or being able to temporarily re-zero the tool at some position other than "jaws closed" in order to directly measure the difference between two length.

You're also at the mercy of battery life, temperature drift in the electronics, and just a higher level of complexity in general. That being said, I'd be comfortable using a good-quality example of either type.
