When people argue about the best 2D Mario it's usually a close call between Super Mario 3 (SM3) and Super Mario World (SMW), with SMW typically winning. At least to my experience.
And, look, I get it. SMW is amazing and there's no point to argue about why something should NOT be your favorite thing.
But for me it'll always be SM3. The amount of variety in the levels, with each world having a distinct theme is something that SMW doesn't come close. Same goes for powerups.
