I think this is exactly it. As someone who has been using solely DuckDuckGo for a couple years, including for technical searches (I'm a software developer), I find using Google noticeably frustrating because Google doesn't give me the results I'm looking for but DDG does.

I think I'm just used to the nuances of DDG where others (who currently use Google) are used to the nuances of Google. You get used to crafting search queries in a specific way, and having to change it is noticeable.
