Yes, it’s good, however you need to be more specific with your query for DDG to return good result.
If you’re interested in other privacy respecting search engines, there’s Searxng and Kagi (paid).
Hell yeah. I consider myself privacy paranoid and have been using DuckDuckGo for 5 years without any problems so far. It is pretty strict about its privacy policy.
I prefer using DDG or Firefox, however my device I lower end and I find that Brave works best on it.
But I use DDG for my search engine.
Brave had some dodgy stuff at the start with their crypto weirdness. I think there owner was involved in questionable data practices at his last company. Personally, I would expect someone running a privacy company to have integrity and not compromise on those values in previous ventures.
It’s better than google, and so it’s a good start.
