I think google is best as compared to other search engines and google carry first priority in order to search something. Some may think that Yahoo has better results than Google, but the problem with it is that the main page is littered with extra junk that only confuses the person looking to perform a simple search. On the other hand, Google.com features the search bar and little else, making it abundantly clear to the user that searching is the primary function of the site.
Google is Best !!
