I should probably add that I know everything I've said isn't convincing to a skeptic. Ultimately it comes down to: I know I can think of the quantum state as being really real, and that will work totally fine. I find that style of thinking is effective for me, and intuitively compelling, so I do it.
Every once in awhile I'll run into someone pointing out the philosophically fraught underpinnings of assuming reality is real or whatever, and I basically won't care because my goal is to be effective; not to be Descartes-level-certain about everything.
An example of something that would make me care is if QBism contained some key conceptual trick that made problems easier, and gradually many papers started using it because of this advantage. Or, of course, if there was an experiment distinguishing between interpretations.
