I never said they can beat a Shichibukai, I said they are on a Shichibukai level; but since there is a huge range in the powers of that group, I'd say the Supernovas are somewhere in between. Above Buggy and Moriah, next to Crocodile (pre-timeskip) and Kuma (given how easy it's now to defeat a Pacifista, I don't think Kuma could still be considered super strong), but below Mihawk and Hancock.
