It all depends on the brand, you just have to research which brand you buy into.
I got a pair of Solovairs which have been wonderful thus far. They used to produce the OG 1970 Doc Marten before they flipped over to Chinese production, so the solovairs can still be resoled with a local cobbler and the materials are quality too (shoelaces were meh but those are cheap to replace).
So basically NPS Solovair, and Gripfast are solid lines of shoes to choose from for quality boot build.
