'The ducks are always greener' →
Being able to quickly try an unhelpful DuckDuckGo search on Google almost always returns equally unhelpful Google results, confirming that the results I got from DuckDuckGo are crappy because web search just sucks these days.
I can't remember when I switched to DuckDuckGo. It might even be more than a couple of years by now, and ever since it became a default option for search in iOS and OS X I haven't looked back. It's great.
