I have nothing against Marble Garden Zone, but I do hate crushing deaths. Need I say more? S3&K delivers on all fronts. It's epic as hell and almost perfect. It's this "almostness" that can be a real pain. Take for example the Eggman boss sprite in FBZ, the guardian in Sandopolis Zone or even Mecha Sonic, who shouldn't have been fought by the Master Emerald altar/socket but in space or at least in the air. But really, Sonic 3 has brought so much to the table. I love how Competition mode got its own original zones, that there are two versions of Knuckles' theme and its wide range of musical styles in general. It's your favourite memory in game form.
