It's just that Overconfidence gives you very generous benefits no matter what kind of team your opponent plays, wheras with shed skin, it's only going to help you if you get statussed to begin with (and if you have terrible luck, it's not going to help you at all.)
I can see the merit in using it, but Overconfidence is just much too tempting.
