When Yoshi eats shells he gains new abilities depending on the shells.
Can be used to reach unreachable areas.
Can walk on things Mario can't.
Can be used to solve puzzles and access new routes in the game Mario can't

Not to mention Mario World is just a far bigger and better game than Mario 3, whose huge sprawling levels shit all over Mario 3's tiny simplistic ones.
With better tighter controls and gameplay focused on exploration and puzzle solving rather than brain-dead running from left to right.
Mario World rapes Mario 3 so hard it's honestly painful to watch.
