I found a blind test. you type in a search word and results from google, yahoo, & bing are presented.

you don't which is which and have to select the one you prefer. i used it five times, bing my faovurite 3 out 5 times, google 2 times

Compare your search: Bing vs Google vs Yahoo

post your results either here on the site. i like to see how people are in comparison
