I've been using Brave since I read the article published here about which of the browsers were more privacy focused (and didn't track you etc), and have been using the Brave search engine since it was released as Beta.
I'd say 90% of the searches I make are all catered for with Brave's engine, and I seldom have to go to Google to do a search. Things that are specific to me (such as when does a specific shop in a specific location open) are better served by Google than Brave. But to get my work done, to look for how to do a specific coding thingymajig, Brave is actually quite good. Better than DuckDuckGo in all fairness.
