I tried using DDG for a few weeks, and I had the same experience as you. I frequently found myself doing the same search on Google to see if there were more results, but the biggest issue for me was speed - both Google and Bing are blazingly fast, and I found myself being annoyed with the noticable delay in DDG.
There are typically more results on Google. But the extra results are usually of a far lower quality (often just spam sites, or other grabage).
I'm very satisfied with using DDG as my primary search engine. And when I feel my search results aren't finding what I need, I might go to Google and wade through the garbage to try to find the gem I'm looking for. But it's rarely worth it.
