@Generic.Archdemon 3 of Gintama's seasons are in the top 10 of MAL top anime of all time and number 11 is a fourth Gintama thing and the original Gintama run of 201 episodes is number 15 with number 14 being another Gintama season. Its safe to say that, at least to MAL, Gintama is the third best ever series besides FMAB and Steins:Gate.
