The principle of Occam's Razor states that, all things being equal, the simplest explanation is usually the right one. So it stands to reason that the driver who wins the championship must be the best, right? Well, that's assuming all things are equal, and of course in reality they seldom are.

After a hard-fought season, Autosport magazine asked each of the team principals in Formula One to anonymously rank who they thought was the best driver, awarding race points to their top ten choices. The result? Sebastian Vettel came out on top, nine points ahead of world champion Jenson Button. In other words, if all things actually were equal, those in the know would have placed Vettel as champion in Button's stead.

For his part, Vettel – who came second in this year's standings and, it should be noted, secured the Nations' Cup at the Race of Champions alongside Michael Schumacher – was pleased with the vote of confidence. But he's determined to take the fight back to the track for next season, which is already shaping up to be one of the most exciting yet.

So do you think the bosses are right? We've placed a little poll of our own after the jump, and invite you to place your own vote.
