Basically, it's pretty much equivalent, except that the key binding
approach seems a bit more general in that the original command that
would normally have been triggered by KEY is executed automatically if
no predicate matches.  With a DWIM wrapper command, you have to look
that up first and put it in the command as fallback.  And you'd probably
have to manually set this-command/last-command in order to keep the
wrapper out but only the "real" commands which you have to call
interactively...

Another really cool feature with Stefan's approach is that `C-h k' in
some special context matched by one of the predicates will show the docs
of the command in that context.  With a wrapper, you have to write your
own docstring explaining all possible contexts and actions.

Bye,
