I can’t decide if I agree with Button or not. His first 7 races in 09 were incredible, and he had another two podiums later on. He did lose a lot of ground to Barrichello in quali, and that was a weakness that seemed strange at the time as he’d always struck me as a great qualifier until GB 09 onwards. But I’m not sure if his race performances were weak- he was hampered by a car that couldn’t be developed at the rate of just about every other team, and in the mid-season the grid was swamped by a large number of winners and potential winners. In 11 he had the benefit of a consistantly quick car, and his results were certainly more consistent, getting more podiums that season that 09 and 04, but whether that was car dependant I don’t know. Another argument is that in 09 he didn’t even get as many podiums as in 04, which was anpther often forgotten great season for him.
I don’t know about Kimi- he was very good in 07, not sure if he was better in 05 or 03.
I agree with Hamilton being better in 07.
