"According to the series' original author, Akira Toriyama, in terms of power, Goku as a Super Saiyan God would be a 6, Beerus would be a 10, and Whis would be a 15."

I'd say Superman isn't even in the two digit span anymore... I don't know, the DB movies don't depict much about their characters strengths. But knowing about Superman's strength, I can't think of any being that can be stronger than him, aside from the Presence and other godlike existences.
