In day-to-day machining, probably vernier is more error-prone.
However, in a seldom dug into toolbox, where batteries go to die, you bet your butt, I've verniers.
Also, there apparently are ONE HELL of alot of fake Mitutoyo products in existence, and that means an aweful lot of fake accuracy is being calibrated-to.

Yeah thanks for the heads up, I've seen a bunch on Amazon for ex.
These are real, we get them from an official reseller of mitutoyo, listed on their site (Newport.com). My machinists have been bitten before in their storied careers, we have an inconel reference block they measure to, even has expected dimensions at whatever current temperature is engraved on it.
Just checked Mitutoyo, now it looks like they have a specially carbide-tipped model that I kinda want, since I'm naughty and scribe my parts lol (573-677-20)
