”If you use Google and are happy with it, you have no reason to switch engines. Simply put, Google is an excellent search tool. It scored at or near the top in every search category we tested, including the standard search for text information, as well as our searches for videos, images, news, blog postings, and local info. While other services performed as well or slightly better in specific areas, only Google aced virtually every test we threw at it.
