@full-throttle-f1 – Well, it’s possible that Vettel is the best. He after all, is the triple F1 world champion, in this supposedly “competitive” era, something people use against Schumacher. I wouldn’t rule out Kimi either, given his good comeback year and unlucky 2003/2005. Basically, Vettel, Alonso, Raikkonen and Hamilton are all really close over the course of their careers.
And I don’t see how JB or DaveF1 is ruining the thread by saying Button’s pre-2009 record is unimpressive. I don’t think Button is the worst champion ever, but some people are going by the champions they have seen, so have limited their choice to the last 15-20 years (e.g. Todfod). Have any of the 4 drivers mentioned above had a season like Button’s in 2001 or 2008? Nope.
