another good reason to use an emulator over the actual hardware is, when you try to extract some graphical data from it, or to study in closer detail how does a game work. you can't do that on the psp's small screen and you don't have any additional options such as pause whenever you want, debug options etc.
taking screenshots, making videos and extracting graphics is almost impossible without hacked firmware, and even that one's very slow for that.
