Personally, I prefer CoffeeScript. The code gets more concise, it stimulates a coding style that's more objective and less "enterprisy" than TypeScript with all the excessive OO stuff. A simpler and more concise language attracts more contributors overtime. However, TypeScript has clearly won and static typing can help a lot with autocomplete stuff, so there is no point fighting back.
