Yes, sometimes that has problems.
No, the search results aren’t always as good.
Yes, I sometimes fall back to Google.
Yes, I still think it’s worth it.
Agreed. DDG is my default search engine on all of devices. Once per day, results are just not great and I switch over to Google. It mostly gets the job done. Plus, since most of my searches now are European focused, the results are sometimes better with DDG. Companies and People that are Europe based have a higher page rank than a USA person or company. Same for beers for which I search often for various beers.
