Supergirl vs. Wonder Women

Well, both have at various times been called female versions of the Man of Steel, so if the two came to conflict, which would win?

Would Wonder Woman whip the opposition, or does Super girl have the skills to triumph?

supergirl has more powers but less expeirience, it's close but i think that supergirl would still triumph. plus supergirl is a female version of superman just a young one as well
