They invoke 2 different interfaces between Emacs and GDB.  Depending
on what version of GDB you have there, "M-x gdb" might not be the best
choice, because it needs GDB 7.0 or later.

There's also this comment in gdb-mi.el, which is what "M-x gdb" uses:

  ;;; macOS:

  ;; GDB in Emacs on macOS works best with FSF GDB as Apple have made
  ;; some changes to the version that they include as part of macOS.
  ;; This requires GDB version 7.0 or later as earlier versions do not
  ;; compile on macOS.
