There is no winner in this discussion. I just learned thru years of doing that you/// I do not uses an extension lens to over zoom the original lens. It leads to poorer quality and under magnification. The more glass you add the worse the quality you get so use the lens to extend the range not overlap it.
In the future, I will be selling Raynox and Olympus lenses with my adapter, and I will not sell what I will not shoot with. The only Raynox lenses I plan to carry are the DCR1540, DCR6600 and the DCR250.
