I like sudoku when it's easy, because it makes me feel smart. But ideologically, I don't like sudoku because it puts crossword writers out of business and sucks the soul of of newspaper grid puzzles. I usually suck at crosswords, but when I actually do a whole puzzle, it feels more satisfying than solving a sudoku. Word searches are easier than crossword puzzles, but they're not as fun, because you're just picking out words, whereas with a crossword puzzle, you're creating words where none existed before. And in the newspaper, no less.
So it's a tie, I guess.
