Search engines are supposed to be non sectarian and impartial. The best ones should offer, first of all, the most popular sites, as well as those more relevant to the topic being searched.

Google’s easy-to-use interface and personalized user experience comes at a cost. They are politically biased and go as far as to censor or push further back those not agreeing with their political views. I've confirmed this comparing their search results from other more relevant and impartial search engines.

Furthermore, it’s no secret the search engine giant catalogs the browsing habits of its users and shares that information with advertisers and other interested parties.

Bing is a superior non-biased search engine. In addition, Bing image search is superior to its Google rival’s and much more intuitive.

Swisscows is a unique option on my personal list, billing itself as a family-friendly semantic search engine. They also pride themselves in respecting users’ privacy, never collecting, storing or tracking data. It uses artificial intelligence to determine the context of a user’s query based on semantic data recognition that give faster "answers" to queries. In addition, Swisscows does not store users' data.
