By this argument, 3D perspective is non-realist, because a cube looks like a square from some perspectives and a hexagon from others – it depends on your point of view!
MWI is the most realist theory, because it says that everything is there when not being observed – in fact, it eliminates the concept of observation entirely. I think the tricky thing here is that MWI says that you are part of the system, which means that the intuition you've built up around collapse theories (where the “observer” has a privileged position outside and above the bits of physics they're “observing”) kind of falls over.

Wikipedia thinks it's realist.
