I only like the SNES version of SMB 3.
All the NES versions of 1, 2 (Japan), and 2 (USA) are better.
Though, the fact that you were given 5 lives instead of 3 was better to me. And unlike most people, I like the save feature just fine. Because I know I won't have a lot of time to devote to playing a game as long as Super Mario Bros. 3 straight through in one sitting.
