My experience has been the exact opposite. As soon as I need to look up something very specific or niche DDG does not deliver and that's when I need it the most.
Google's index is 4x bigger (I can't recall the specific numbers but it was mentioned in a recent competition report in the UK)- I'd expect Google to be better at returning long tail stuff where perhaps Bing (and thus DDG) simply don't have the depth of documents to return.
/edit here's the quote/source
"We found that Google’s index is larger than that of Bing in terms of number of pages in the index. Based on submissions from these parties, Google’s index contains around [500 -600 billion] pages and Microsoft’s index contains around [100- 200 billion] pages."
