White chocolate, milk chocolate or dark chocolate - which is the most tasty?

Tweet

I like eating chocolate and was just wondering what the general views of what the most popular type of chocolate is. I can't quite decide which I like the best, I used to only eat milk chocolate and the occasional white chocolate bar and never eat dark chocolate because I thought it taste too bitter. Last year I went to a chocolate shop in Berlin and bought some lovely dark chocolate there but have never found any so nice since. So what do people think, which chocolate is the nicest?
