Mostly: DDG is just a fantastic time-saver. Bang searches from the navigation bar, URLs directly in the SERP, no Google ad spam pushing organic search well below the fold, images accessible from the image page, and of course, no bubbling or tracking.
Yes, occasionally I need to offer slightly more specificity in my searches, which really isn't a challenge.
And yes, the list of shortcomings I'd made on HN in 2014 still largely apply: ranged-date searches, specific media collections (scientific articles, books), and specific Google tools (ngrams, trends) have me going off DDG. But those are much as HN searches (!hn), Wikipedia (!w), or the online etymological dictionary (!etym) a bang away (!gbooks, !trends, !ngrams).
Technical search quality is as good or better than Google at this point.
Archive collection, notably in older content, occasionally weaker.
