TBH, I don't know enough about the differences.  UCRT is supposed to
be more modern, and so more compatible with ANSI C and perhaps also
with Posix.  (However, MinGW has for a very long time a support
library which provides ANSI C compliant implementations of various
functions, so this problem is largely solved even without UCRT.)

The fact that we don't have experts who can answer these questions is
one serious indication that dedicated support persons are needed if we
want to be able to use whatever good features UCRT provides to Emacs's
benefit.
