I have several boxes full of mics and caliper, digital and analog. I use only Mitutoyo digital calculators. Batteries last forever, never had a failed caliper.
For close work, hard to beat a mic. Look for one that reads to 10ths .0001. These have 10 addition graduations on the body shaft. Also don't buy a mic that has a plastic locking lever. They break.
I have mics from Starret, Mitutouo, Brown & Sharp and Flowler, plus a couple of others. I can't tell them apart for accuracy.
Beware though, there are fake mitutoyo caliper clones. Google that so you can tell the difference.
Starrett is now sourcing some of their stuff from China. google that if you like.
And oddly enough, one of my most accurate mics is this one.

You can find that same HF mic re-labeled by some prestigious brands for a lot more money.
