User blog:Imhungry4444/Shichibukai really that powerful?

Is it safe to say that the Shichibukai r the most powerful pirates in Paradise? i mean their only competition in the power ranks would probably be up in coming rookies like the supernovas. plus, we know an average supernova or up and coming rookie wouldnt stand a chance against a Shichibukai(besides luffy but thats why i said an average). Am i right or am i wrong?
