So multiply that times 20 such little modes, and note that
self-insert-command is probably the most heavily-used command in
emacs...

It's far better, because it follows the normal scoping rules of keymaps
(which is even more important in the case of minor mode maps), allowing
such overrides to be very narrowly targetted.  defadvice is a clumsy and
blunt tool by comparison.
