I widely prefer Super Mario World. Better music, better level design, loved that you could replay the levels without restarting the game, loved the secret exits, the world map, Yoshi, and the fact that it was not extremely hard.
SMW was my favorite Mario for about a year (Galaxy replaced it) and is still my favorite 2D Mario. SMB3 is around...my fifth favorite Mario I think.
Top 3 favorite games: Super Mario Galaxy, The Sims 2 (PC), The Legend of Zelda: The Wind Waker
