Senna was a VERY interesting figure. For whatever reason, the press eats up his virtuosity. The big incident where I feel he was on the right side of history was his should-have-been-a-win at the Suzuka GP in 1989: https://en.wikipedia.org/wiki/1989_Japanese_Grand_Prix and his mistreatment at the hands of Jean-Marie Balestre. According to wikipedia, Balestre admitted it:
"Years later, after leaving the presidency of FIA, Balestre admitted to having acted to benefit Prost in 1989."[1]
Having said that, Prost was the better racer, and Senna benefits from the halo effect of having died in his prime. He's got some great quotes, and he was definitely mistreated at times which increased his standing as a folk hero, but he was outclassed at almost every step by Prost.
