As all we know there are so many search engines in the world there is different search engine use by the people. There is no doubt that google is good but we can't say that it's best because people use different search engines in different country.
I have used cuil.com for ages now its a great site offering just what you need! Did you know that YouTube is now the 4th largest search engine?
Google, then Yahoo. Then Bing. Then... I don't know, those are the only three I ever work on. I still get random stuff from other smaller engines, though. It's a bonus, I suppose.
if you are in seo than google, yahoo, bing and many more are good for you.bt if you are general user than google is best forever.
