I tend to use DuckDuckGo most of the time, but its quality has collapsed considerably. Google is terrible now and only worth it for reverse image search. I haven’t tried Brave much and SearX-NG was a pain to set up for being a de-facto Google and Bing wrapper. There’s Kagi but I don’t really have $120/yr for a search engine, nor do I want to deal with how they handle logins and session management.
Ecosia and Qwant have been okay for me. Might not be for everyone though.
Qwant and ddg are identical to me
There’s some little differences - for example, Qwant doesn’t spam you with irrelevant “Apple Maps” results on every search, as DDG has for a few years.
