Ixquick for me. It is the same entity as Startpage.
And that has nothing to do with this.
It's not about your privacy. It's about the RESULTS that you see when you search for something.
StartPage is just Google with an anonymizing front end. That helps if you don't want anybody to know that you searched for "Hillary nude", but the results you get are the same.
It's the manipulation of the results that worries me, together with the fact that so many people can be influenced by the first two search results.
