I tried Qwant but I quit after 5 minutes. Their results are horrible, searching for something and the second result is Google and thrid is Instagram? Common!!!
Also, the duck might be a choice if searching for English results but in my language, it simply sucks, the results are either irrelevant or articles older than the internet.

This is pretty much why I'm still forced to use Google's search engine. Their algorithm is simply just better due to the huge amounts of tracking they're doing. Brave browser's privacy features helps in this case I guess, to prevent cross-site cookies.
As with DuckDuckGo, it has the potential. But if I understand correctly, for it to have better and more relevant results, more people need to use it. But then again, not much people use it because the results relevance isn't that good. 🤷
