I think we really will need more details here! Could you elaborate a bit? What would I learn if I spent 25 min researching kagi?
They have a lot of nice features pulled from Google and DDG:

I haven't done any objective tests, so can't really say much about search quality except that it definitely works at least as well as Google for my searches (usually tech or legal stuff), and it doesn't have ads. Whatever I'm looking for is usually the top result if my query is good and it's not something that's ambiguous.
