The QBist stance is that we “know” very little about the underlying reality. One of the only things that Chris Fuchs is willing to accept as an objective property of a quantum system is its Hilbert space dimension.
I doubt it’s sensible to talk about an interpretation of MWI. MWI says that the wavefunction is a real physical object and wavefunction splitting is something that’s genuinely physically occurring. QBism denies that the wavefunction is a real physical object.
