Pilot wave theory might be easy to visualise if you don't consider entanglement, but it suffers from the conceptual problem that it's just many worlds with extra undetectable structure.

The pilot wave is the entire uncollapsed wave-function, exactly like in many worlds. There is also a particle and instant, universe-wide collapse, neither of which are detectable even in theory. Nothing except the wave function affects the dynamics at all.

All three interpretations are 'just the wave function'. What separates them is the metaphysical interpretation of what is 'behind' the wave function.
