I'm certainly not an instrumentalist. But the argument that MWI supporters (and some critics, like Penrose) generally make, and which I've found persuasive, is that MWI is simply what you get if you take quantum mechanics at face value. Theories like GRW have modifications to the well-established formalism that we, as far as I know, have no empirical confirmation of.

There are modified theories, there is no unequivocal "face value".
