I can hardly imagine less compatible interpretations of the same mathematics. I could add Cramer's transactional interpretation and Feynmann's zig-zag in time interpretation. Are all those maps or territories?
Well of course the ontological details are indeed quite incompatible.
The status of QM is still very much 'in the air' at the moment, so we
don't yet know with any degree of certainty. But that can (and
should) change once both theory and observation progresses in the
future.
But most of these interpretations do use some similiar concepts. As I
mentioned, the idea of some sort of 'wave of possibilities' for
instance. Even Bohm's 'only one outcome' still uses the wave concept
(the guiding 'pilot wave'). So it's not as if 'anything goes',
ontologically speaking. Progress is being made.

The example I gave of the Alain Aspect experiments (testing Bell
inequality) did point to proof of some quite specific features -
according to these experiments, all future theories replacing QM would
have to have either indeterminism
or non-locality. So progress is made...
