Maybe it depends upon the specifics, but for technical queries I've found DDG to be hands down better than Google for years at this point. Google used to be great, but with the dropping of both code search and specific matching even when using quotes, I've found it to be pretty terrible in recent years compared with a decade back.

DDG had a period a few months ago where when I toggled on my country-specific search, the results were _spectacular_, language specific, relevant. Then it went away again. :/

It did make me hopeful that they're working on something to improve this.

I used DDG as my primary for a full year (2019) after using it on and off for several years, but I went back to Google and Bing this year. DDG has terrible results and about half the time I ended up using Google anyways. Image search is a travesty; current events often produce zero results.
