I've been using DDG pretty much exclusively for the past couple years now, so yes it works just fine. If you want to see what another search engine would have shown you, you can use a "bang" , and search wikipedia or reddit for example. Pretty useful !
I find that brave still has the same problem as google a lot of the times though. If I search for info about something in Zelda for instance I get the same useless IGN and Gamerant articles rather than a wiki page or actually useful information.
I have yet to find a search engine that doesn't have this problem.
