Although I hate the Brave browser, the search engine is the most useful of the others. It gives me the most correct results compared to the others, even it sometimes ignores the quality resources.
I wonder your opinion about the search engine. Do you have any negative ones?
I replaced all of my searches with Andi and it was as advertised. Didn't beat around the bush at all. Though Brave is a lot better with programming questions and obscure references. I went back and forth testing each out.
I use Andi as main search by default, but naturally I use also others, eg. Startpage for images, also Mojeek among others, apart some specific ones for Forums, Pixabay, Wikies, etc.. I always find what I search
Whoogle also use the Google search API, like Startpage. But Whoogle is FOSS, you can selfhost it, or use one of it's open instances. But this you must see by yoursel which works best for you.
For other search engines, you can look in the Vivaldi Forum, there is maybe the most complete list of search engines you can find, complete with insert code, made by an user
