Penrose's ideas are a bit more in line with what I'd bet on. So there's some kind of actual nonlocal entanglement (tiny quantum mechanical wormholes that aren't useful for communication or something like that) with a physical process that happens once the entanglement has grown large enough which causes collapse (the emission of a virtual graviton at around the fermi mass of difference between the states being something plausibly at the right kind of scale). And this should all in principle be possible to study (and there has finally been some headlines about studies that have attempted to look for these kinds of effects). Pilot wave theory just shows that there's an alternative possible explanation for QM which doesn't have any many-worlds interpretation which is another thing which cuts the legs out from under the idea that WMI is the "null hypothesis". We don't know how to make that theory relativistic, but our lack of knowledge doesn't mean that the interpretation is wrong. We can't look at conventional Hilbert-space interpretations of QM and walk away saying that it must be correct, when there's other math that works basically the same. We picked the math that worked the best for us to make predictions, but now we're making the jump to claim that the math must be the reality which seems obvious to me to be a mixing up the map and the terrain.
