I'll put in a vote for Zhuyin: - more consistent (no confusing between the two sounds for "u" for example). - better IMEs - you can filter characters by tone, impossible to do with Google Pinyin for example. - can be used to type Simplified and Traditional - no interference/preconceptions from other languages written in the latin alphabet.
