A few words from Mark Mahaney of Citigroup explaining methodology of their study..
Over the past two weeks, we conducted 200 queries across the three major Search engines–Google, Yahoo! and Bing. Most of the queries we picked came from Google Zeitgeist, Microsoft’s xRank and Yahoo! Buzz, along with some personal queries. These queries spanned multiple categories, including Entertainment, Health, Local, News, Retail, Sports, Travel and Other.
After conducting the same query across all three Search sites, we picked a winner based on:
1) relevancy of the organic search results; and
2) robustness of the search experience, which included factors such as image and video inclusion, Search Assist, and Site Breakout.
Organic search as mentioned by Mr. Mark is the search result area of any Search Engine and rest of the area is for dynamic advertisements.
Here are the results..

The results show that Bing is really trying to compete but Yahoo struggled.
The story is not the same when it comes to individuals liking...
Polls conducted by different websites and portals show that Bing is equally preferred as much as Google is. So the life wont be easy for Google any more while Yahoo stands no where in the competition.
