Pacifica is my favorite world ultimately because of the overall feel of the area. I love how technically it's a water area but it has it's own little special elements about it. Plus it has some of my favorite levels in the game (Dingy Drain Pipe and Sunken Spruce). Krematoa on the other hand has always kind of bored me and levels like Rocket Rush and Tyrant Twin Tussle aggravate me.
