The difference would be in the case of a simulated consciousness, I would been dead and wouldn't get to experience any of the pleasure that fake-me experiences, for making a simulated consciousness is the same as making a philosophical zombie.
A philosophical zombie is an incoherent concept. The idea that your consciousness could disappear while leaving all of your external behaviors unchanged makes no sense. Your consciousness affects your external behaviors; if you were not conscious, your external behaviors would be different.
