I have always been partial to the S-Mart ending, the other ending was alright also, but I much prefer the S-Mart. It is also better suited for the possibility of a sequel. What would be interesting, though I am not sure how it could be done, would be to go about with the apocaliptic ending, then to fade to the S-mart scene where Ash is telling the guy his story. It has been a while since I have seen the movie, so I am not sure of the actual dialogue there, so it may be impossible to do. This way it would be like Ash was making his story more elaborate and adding things to it. Though I think I would give preference to the dream sequence then waking up and realizing he over slept over the regular over slept ending. The more scenes the better when it comes to evil dead.
