Seconding this. DDG is awesome. The zero-click info is often very nice, I love the keyboard shortcuts (though there's a google keyboard shortcuts experiment), and !bang[1] is really awesome. There's a bunch of other occasionally-useful goodies[2]. It'll do disambiguation if you search something with many meanings (eg. Ruby). Infinite pagination.
I switched a month or 2 ago, and I've been very happy. And if I search for something and don't like the results, I hit / (the keyboard shortcut to select the text of the search box), hit right-arrow (to get my cursor to the end of the search box), add a "!g" to the end, and hit enter. And then I usually find that google's results are just as bad :)
