I received an SNES for Christmas in 1991 and loved Super Mario World. I was a huge fan of the NES trilogy and had high expectations. Super Mario World lived up to all of them.

A year later, I finally played Sonic the Hedgehog on my friend's Genesis. After all the huge hype, I was disappointed. I kept asking him, "How do I go really fast like in the commercial??" I guess Sega's commercials were misleading.

Looking back, I'd say Super Mario World is a well thought-out, finely-crafted classic, whereas Sonic the Hedgehog is a standard platformer that happened to be backed by Sega's marketing.
