Of course the divine spirits of the nasuverse are stronger than heretic gods of campione not to mention most gods of dxd universe. In their original universe they are nerfed due to counterforce acting on them. Even among them skadi ruled over a lost belt where she was the only god becoming a semi monotheistic godking who gathered faith over millenia. Coupled with infinite mana supply from mc yeah she could probably solo all the seven campiones together by herself given enough time and preparation.
