I would say that anyone of the writers listed are far, far superior to Bendis IMO (OK, I have only read very little of Aaron's work, and I find it weaker than the others on the list).... and Parker is probably up there with Slott and Gage as Marvel's best bunch of writers.
Why does a writer have to be known or a 'big name' in order to sell a title? Shouldn't their work be the best way to gauge the quality? And, as Telos said, these writers have all shown that they know the characters and the MU much better than Bendis has ever shown. They could write circles around him no matter of their status in the hierarchy of popular writers.
