Best JJ1 Level: The turtemple one with the underground maze. I just like the turtemple one overall. And the Lagunicus one. And if it counts, the 3D bonus levels (all of them, they're just awesome)

Worst JJ1 Level: I never really liked some of the ones in the 'bonus' episodes (whatever you call them), particularly Raneforus and some other planet with a lot of colors, maybe Exoticus (not sure).

Best JJ2 Level: Back when I only used to play SP I liked the Colonius, Psych, and Beach levels (all of them). And Bad Pitt.

Worst JJ2 levels. Battle1 Uhh...The unfinished Psych one, The training level, and maybe one of the diamondus ones (those bees are just SFSCF$#HATE annoying, especially since they respawn).
