Google is best search engine I experienced because it gives thousands of results in few seconds its service is extremely fast and it is designed so simply, it is to use and its No#1 search engine of the world.
Its very helpful to its users.
It is Awesome search engine with a lot of extra features than other browsers.
One thing that I liked most in it is that on Special Days(e.g Mother Day, Christmas e.t.c) the front page of serch engine is full of entertainment because the word google is writen in so awesome styles.
