Type why you think the game is better and what you like about it!
Ooh man this is a tough matchup but I have to side with Super Mario World considering it's my favorite Mario game ever. This game brings back so many memories for me and it was actually the second Mario game I've played in my life (yep before SMB2 and SMB3). It has a massive world, so many secrets, tons of unique bosses, and an awesome soundtrack that makes me keep coming back for more! Not to mention the good challenge Star World can give you. Super Mario Bros. 3 is an amazing game as well and it has so much charm with it's unique worlds. However, Super Mario World offers a much more bigger experience. Oh, and it introduces pretty much my favorite character in the series: Yoshi.

It's not a choice. It's just a comparison between those two games up above. Please don't go off-topic.
