Well grammar nazis aside, here is my opinion:
Neither... you should keep it. Even with perfect emulation, something just gets lost when you aren't playing on the original console. Years from now you'll feel the urge to play playstation and kick yourself for getting rid of it. You also never know what will happen years from now. The power glove and R.O.B. were worthless trash when they came out. Now you can't find either on ebay for less than 100 bucks even though they are still just as useless.
You can put a game console, it's accessories and all your games in a very small box and set it aside. You'll never miss the space.
Personally I still have every single console and portable I've ever owned, including games and accessories, save the oddball that broke or something. I intend to keep it that way. If nothing else you can put up a nice shelf and put all your old gaming stuff up as decoration.
