Seriously, I did all the research and it seems like Usagi would end up winning. If Madoka gets a wish during the fight from Kyubey, Usagi should be allowed one from the Silver Crystal. And, as are Death Battle rules, Usagi knew nothing about her opponent, or her world. So she would have no idea what this whole thing about witches was, so wishing for Madoka's wish to be undone....really has no real way of knowing what this thing about witches, was so Usagi could have thought it was unimportant, and reverted Madoka to her previous form.

If Goddess Madoka had not been used at all, Usagi would have won quicker. If Usagi dosn't get a wish from the silver Crystal, than Madoka would not be allowed to get a wish from Kyubey and go to her goddess form. So there is no real way to include Goddess Madoka without the Silver Crystal coming into play to undo it.
