DuckDuckGo is already better than Google in some areas at least. You also have SymbolHound which made it a point to support searching for nonalphanumeric characters.
Mmmh. I do use DuckDuckGo as my main search engine, but I'm sorry to say: I unfortunately have to fall back to Google quite often to find what I'm looking for.
I'd be curious to know where they are better than Google.
