How good a win was Tyson Fury's second victory over Dereck Chisora?

[W1LL]

Considering Chisora has been at/around Contender level for many years now. He is a real tough customer and has shown he has longevity at the level he's at. At that stage Fury's biggest win was Steve Cunningham, while Chisora had already put up a great fight against Vitali Klitschko, and also shared a ring with David Haye. Had also taken Malik Scott's 0, beaten the legendary Danny Williams and got robbed against a Drago-like Robert Helenius. How highly do you rate this victory for Fury? Considering he put on a flawless performance and made Chisora quit in his corner, totally outclassed.
