I’ve been a machinist/tool maker for 50 years including owning my own shop for the last 20 years.
I use Brown and Sharpe dial calipers and Mitutoyo digital calipers.
My 24” vernier calipers are Starett.
I use Brown and Sharpe micrometers.
I have used and owned many other brands over the years, but these are the brands I depend on.
YMMV
