Yeah, I've been giving DDG a try for the last few weeks again. For "I want to look for keywords" I use DDG and find it does well. For "I want to search a structured database", Google still wins because of its above-the-fold no-article "this is what you're looking for" results.

Like, if I type a math formula or "what's the population of Alberta", the Google result is just the number, not a link to the result.

Or if I want to search for a product or local business.
