Who are some famous bull riders?

Everyone has their own opinion. There is a great difference between 'Who is the best bullfighter?' and 'Who was the most popular bullfighter?' Sometimes it is the same person, sometimes not. For best bullfighter ever, many people would choose Juan Belmonte or Manolete. For most popular bullfighter El Cordobes might be the choice. He was not a particularly good or artistic fighter but became quite popular a few decades back because of his reckless attitude and daring in the bullring. Belmonte and Manolete have been long dead and El Cordobes has been retired now for a number of years.
