Same here. I used DDG a couple of years ago, for about 2 months. I also ended up going back to Google for at least 30% of my queries. As a result of the reduction in productivity, I decided to switch back to Google. Besides the anonymity there are a couple of features I like, but content wise there is no match to Google at the moment. One thing I like is the bang feature (!stackoverflow hello world), but realize that Chromium offers something more convenient built-in, which I also rarely use in practice.

Still waiting for something that brings the best of both worlds.
