Better than DDG Rated 4 out of 5 stars
Google is still the best search engine. There is duckduckgo but it lacks the ability to sort results by date range which is essential to me. Startpage lets me use Google without sacrificing my privacy however I'm knocking off a star because they use GoDaddy (evil Sopa supporters) for their SSL.
P.S. What proside saying about Google leaving a cookie when you use Startpage is totally wrong. They cannot track you through Startpage or set a cookie from a Startpage search. Startpage gets the results from Google then sends them to you. Google doesn't see your IP or anything about you. Even your ISP cannot see what is being searched for as the data to and from Startpage is encrypted.
For extra protection against tracking you should always disallow third party cookies in Firefox and install the DoNotTrack addon from Abine.
