Even though many think Schumacher is higher than anyone else, sure he is damn good, but it's not all that simple, only reason for example Räikkönen didn't beat him to the championship was unreliable car - and still with that he only lost by what, 2 points? Alonso did beat him, Häkkinen did beat him, MS is about the same level as all of them. And none of them come close to what Senna has done.
