There is no 'best F1 driver to ever live'. That's right, even Senna was not the best F1 driver to ever live. There is rather a group of 'best F1 drivers to ever live' and you can pick and choose from that group depending on era, etc.
Btw, If you don't think Schumacher was one of the best, then you need to rethink your priorities.
I'm not going to delve into a defensive argument on Vettel again, but the people writing him off this season are very silly. This is his first poor season at the front.
It was really a rhetorical sorta question. Nobody is stupid enough to suggest that there is one, clearly defined Ultimate Driver That Ever Lived, and it certainly wasn't me, so cool it. And there's no need to tell me to "rethink my priorities", either. We're all just sharing opinions here, so there's no need to be aggressive.
Nobody* is writing Vettel off, but he has had a disappointing season by his standards, don't you agree? For those of us who have believed all along that Hamilton and Alonso are still the better overall drivers, it just adds a little fuel to the fire in that belief, that's all. He's still a great driver.
* Well I guess some people are, but those people are nuts.
