Super Mario World

Super Mario World.

I honestly do not like either one too much.
Im a weird mario fan I think Mario 2 is better than both of those.
but if I had to pick id go with 3.

I have to go with Super Mario Bros. 3...
Super Mario World just seems kind of lazy in comparison...

I think that might be because SMB3 had a lot more limitations with the NES, so what they did was more impressive in comparison.

Mario 3 I thought had better levels overall but it's a tough one, I love both games a lot.

Super Mario World had better levels, power ups, gameplay, and the soundtrack is phenomenal.

Easily Mario World! The level design is flawless, the game is full of content and the controls are so tight! Mario Bros 3 is good, but it's a joke compared to the legendary Mario World!

Super Mario Bros. 3, especially if you count Super Mario Advance 4, that game includes both the cape and tanooki!

I think I might go with 3, but I do love me some four particularly all the hidden levels.
