Well, in my experience, the quality of the search results I get from Google overall has fallen quite a lot over the last few years, to the point where for any given search, DDG is far more likely to surface what I'm looking for.
This isn't just about certain cherry-picked examples.
Even being right 99.9% of billions of queries means being wrong many times.
This calls for statistical analysis, not cherry picking examples or asymmetric sample like "given a bad result from X, Y does better."
