Agree with Rusty... unless you have ball tips for your caliper. I have both, I use my analog more because it is always ready.
the digital should not be stored with the batteries installed, normally takes several button type that can leak & corrode & cost $$.
but I use digital when I want MM/IN conversion or quick check of sizes, like checking 30+ allen wrenches, unmarked, mixed odds & ends.
just press button to switch between MM or IN.
