The differentiation is that you're the only one having that subjective experience and you're stuck with it, so as far as you're concerned the rest of the world is a construct around you and you might as well make it an experience with which you're at least content. If we started to have neural linking that mimics exactly the entirety of another person's subjective experience, perhaps we'd prefer being brains in vats experiencing a handful of human TV channels while the "top" whatever live it themselves. But then again at that point why not experience an eagle's flight, a whale's dive, the sense of scale of an ant, the computing of some supercomputer, etc.. and whatever we currently consider to be topping our experiences would also be relative.
