Wasn't huge on Yoshi's Island mechanics, and didn't play through too much of the game, so I can't comment on there. I voted for SMW, feeling that overall that's probably the best even though SMB3 was my favorite.
Personally, I think 3 and Yoshi's Island are the best, though I'd like to replay World as I've not played it for a good while, but as a kid I always like 3 more than world
I love every game on this list, except for Yoshi's Island, which I genuinely hate.

hahaha i actually saw these guys live!! Was my last pre-pandemic show :(
They, however, did NOT play this song and i was pretty upset about it (not really tho bc the show was awesome as a whole.) They even had insaneintherain music as a guest performer!
