I played through them for the first time a few months ago and with no nostalgia at all, I'd say: 2>1>3. 2 had good (not great) level design, but the worlds were nice and controls were good. In the first, it was a nice platformer, but the controls leave a lot to be desired. 3 was too gimmicky, but still good. None of them are what I'd call classics though.
