Google is the king, but they are always making changes. Don't be afraid to try Bing and other SEs though.
I find the Bing homepage to be most splendid, however I find the services Google provides are superior to Bing.
That is little bit shocking... Bing is having its own reputation. It is not small search engine then why they take results from google. From my point of view, Bing is having it's own algorithm and it does not take any result from Google. Of course Google is best.
