It might be just me but I don't get why people on here tend to be critical about DDG's usability. I made the switch a year and a half back and I seriously don't miss anything. There are some niche cases where it doesn't work, you can just use the bangs in those cases. The trade-off, like you said, is well worth it. (Upon typing this, I realize I'm just echoing your comment. Either way, leaving this up to provide one…
When I first tried DDG - more than 5 years ago - it was worse. I was unable to find the answers I needed and ended up back at google. I tried off and on a few times over the years, and about a year ago I found it good enough to switch. The few times DDG doesn't find what I need I tried google: it too failed to find what I needed. In short, if you last tried DDG a long time ago try again, it is much better.
I used to be one of those people who when I couldn't find something on the duck would repeat the search with Google. But more and more, especially in the last six months, if I can't find it on Duck, it's not on Google, either.
Duck gives me irrelevant results to those queries. Google gives me irrelevant pop-culture results to those queries.
