My experience is that we reached a point where if DuckDuckGo can’t find something, then neither can Google. For local search Google is still a little better, but they choosen to drown out actual results with ads.
Not my experience for dev related searches. I assume this is because Google has learned I always search for JS stuff and I've gotten used to that so I'm not specific enough in my searches on DDG.
Do you have an example of a search you've done where the results were much better from Google Search than from DuckDuckGo?
