I have to say, I use DDG regularly for search and switched about a month ago. Honestly, I have had little issue with it besides the occasional switch to Google when searching for super random very niche things.
The real trick, is to just start using it and force yourself to. It's really not too bad, and there is always startpage, which you can use as backup.
For reference, I use Firefox on mobile and desktop and when I type in a search I can select which search engine to use. By default I have DDG, and with one click I can get startpage or Google.
Yes, I can't say that there's much I love more than forcing myself use a tool that's "not really too bad." DDG seems like they're really providing a stellar product.
Their product is search that doesn't track you. The search portion is not too bad, as in it does it's job and I feel happy to use it (although not super excited).
However, search is essentially a commodity.
DuckDuckGo has provided additional value which is that you aren't tracked. That, in my opinion, is what makes this a good (stellar) product, that I want to use every day.
The use Bing ads and affiliate links to monetize. Nice, that "they" don't track me, but as soon as I click a link there I will be tracked. That argument is utter Bullshit. Only real plus point is, that even if they track it's not in Googles Data Silo.
