Mario 3 is better than World because of the platforming yeah

Also the controls are tighter and more satisfying

Also the level design is more interesting and diverse. I can name every world in SMB3 and tell you what distinguishes it. SMW I know what the map looks like but honestly all the level designs kinda melt together aside from the backgrounds. What makes Chocolate Island different from Donut Plains other than being brown I don't really know. Forest of Illusion is the only world that feels different to me to be honest (aside from Star World/Special)

Mostly because of the platforming like Leonhart said though.

Honestly I'd probably rather play SMB1 than SMW to say nothing of the vastly superior SMB3.
