This is not the best forum to ask the question. This place is dealing with drafting standards.
Nevertheless, from my experience on the shop floor, if it is "digital vs. analogue" question, I wouldn’t want it any other way, but digital.
If you only interested in picking thr right brand, I was using Starret.
Still, I could be measuring different things different way from how you intend to use the gauge.
So, you will be better off asking Manufacturing / Quality Control people.
Good Luck!
