Regarding Schumacher... Well, in the last 5 years, he won the championship when he clearly had a better car than his rivals, and the rivals themselves were not as strong. Therefore, I don't consider him better than Prost and Senna, who won the same 7 titles between them, competing with each other, plus they had drivers like Piquet, Mansell, and others competing with them.

Although Schumacher is a fan of shaping and a healthy lifestyle, he is still not quite an athlete, just as Formula 1 is not quite a sport. Therefore, it is not entirely appropriate to include him in this poll. But with the phrase about the clearly strongest car for 5 years in a row, you severely exposed yourself: either you are simply a Schumacher hater (he annoyed many people), or you don't understand Formula 1 very well. "The Red Death" was only in 2002 and 2004. In 2003, there were at least 3 equally strong teams, if not more; the Ferraris were definitely third (at least considering the incredible luck and tires). In 2000 and 2001, McLaren's car was only slightly worse, because any reasonable observer will say that if a car performs well in Barcelona, then it is definitely good. After all, that's where everything is tested (driver errors with settings are almost zero), and the track is for pure technique. What track was "the best" for Mika Häkkinen? Exactly. Mika himself, despite his reliability and human decency on the track and in the pits, was not the fastest champion (in recent years, only Hill was slower), although, like all drivers who prefer cars with understeer, he was quite successful.
In general, titles are won only with the strongest car or one of the 2-3 almost equal cars (more often two). The last exception was 1994, and perhaps last season could be considered a half-exception, in which Kimi was simply brilliant, except for a couple of races at the beginning of the championship. But he wouldn't have won the crown if Alonso and Hamilton hadn't been such fools, because with the current reliability and electronics, even a small advantage in pure speed is very difficult to make up for. They were clearly not letting the legacy of Hill rest, who in that very 1994 managed to squander a very good car.
