I typically use Duck Duck Go, but sometimes the search results from it just don't get me the result I need and as soon as I do a Google search, there it is at the top of the search results.
Seconded. It's a fairly frequent occurrence for me. In one extreme instance within the last two weeks I was searching for some very recent news item - I forget now what it was. DDG had ZERO results, and Google had a bunch. That said, I've found a few occasions where DDG gave better results on the same search terms.
DDG also requires putting EVERY search term in double quotes in order to reliably provide usable results, whereas Google doesn't.
That said, I almost always use DDG first, because it seems to honour privacy more, because variety-equals-redundancy-equals-resilience, and because fuck Google.
