(Laughing with myself...) ..... come to think of it, for measuring purposes it doesn't matter what brand or even type, as long as you're measuring what you're using correctly. Sorry for sharing my confusion with you ! I do take many readings for multiple places though, as when you squeeze the calipers there's always very small fluctuations, at least with my hands and the not fancy digital caliper.

When I bought the digital caliper years ago I almost tossed it as it was eating batteries from even not using it. I finally wised up and now only put the battery in when I use it, then remove it when done. The battery has lasted many years now !
