I have similar experience. Upon reflection, when searching, I had some preconceived expectation about the result, maybe a stackoverflow answer, maybe a wiki article, that made me "think" google result was better. But in reality, it was because I was expecting the result, in particular the result from google, before having the result. The longer you use DDG, the less google-specific result I expect. Of course, DDG's search is improving, but I think it is my own search result expectation that leads to the impression that google's search was better. Now I use DDG exclusively.
