I'm not going to vote until I play DK's Jungle Ruins - but here's my order on the others :
1)Magma Mine - Captain Event wasn't that good - but I loved trying to escape the lava!
1)Boo's Horror Castle - Captain Event wasn't that good - but I loved avoiding the boos! (even when they're in front!)
3)Blooper Beach - A nice stage to play in once in a while
3)Toad Road - A nice stage to play in once in a while
5)Bob-omb Factory - Didn't like the Bob-ombs that fell from the sky...
6)Bowser Station - too short, sorry
If I played DK's Jungle Ruins - I still would probably pick Magma Mine over Boo's Horror Castle, just because I like the theme more...
(Theme Wins when it's a tie - all in order from 1-6 (Best to worst))
