I only played some levels of the first DKC, but from what I saw, I'd say Yoshi's Island is far superior in originality, level design and style.
Currently playing: NSMB (Wii)
Waiting for: Super Mario Galaxy 2 (Wii), The Last Story (Wii), Golden Sun (DS), Portal 2 (Wii? or OSX), Metroid: Other M (Wii),
... and of course Zelda (Wii)
