Mario Galaxy 2 is easily the best game in the series, Mario Galaxy 1 a solid number 2. I don't think there is much debate here just given the amount of content and awesome gameplay experiences to be found in those two games, which simply have not been matched in any other 3D Mario games.
Mario 64, Mario World, and Super Mario Bros 3 are all debatable for the third position. I personally prefer Super Mario Bros 3.
As for Mario 3D World, it is a game I would have expected on the 3DS, honestly. I was wondering when the game was first shown if Nintendo had made a mistake. It really is just a sequel to a spinoff game. It is a painfully linear and very stripped down Mario Galaxy game.
Mario Sunshine was easily one of the 2 worst home console Mario game, only rivalled by SMB2 on NES, and that one doesn't even really count.
I describe myself as a little dose of toxic masculinity.
