Over the past 5 years I’ve tried DDG several times. Each time except the last I wanted to stick with it but the results simply didn’t stand up to what I’d see on Google. About 6 months ago (a year? I can’t remember) I switched and haven’t looked back. Now, when I look at google, the results actually look less relevant. As well, the ads on Google have become very obnoxious. I don’t feel like I’m being served the best…
Overall I still believe for sloppily constructed queries for which I want specific results Google seems to read my mind better and produce better results than DDG, but Google is very quirky.
