Diopters add another piece of glass which ultimately degrades quality somewhat, but they don't reduce the amount of light to any significant degree. Extension tubes don't introduce any more glass, but they do reduce the amount of light available. Lens reversal rings work well also, but only if you have a lens that has an aperture ring, which most modern SLR lenses don't. If the lens doesn't have an aperture ring, you are forced to shoot wide open all the time.
