I've had both those MP3 players and I'm actually riding with that Samsung right now. As far as sound quality both are the same. The only down part about the Samsung is that it freezes up and makes this loud screech noise until you reset it, and to reset it you need to poke a button in the back. Other than that, the Samsung is better than the Shuffle because you get a screen in the Samsung and you can organize your Samsung into albums and playlists. So yeah, go get the Samsung its a lot better than the Shuffle.
