Brave is my go-to; I use it all the time with !brave on DuckDuckGo. 

I avoid !g and DuckDuckGo's default search as much as possible. Since DuckDuckGo uses Bing, the results aren't great. 

Interestingly, Brave is building their own independent search index, which is really great and important.

I mainly use DDG to search other sites.  

 Mojeek has their own independent index as well. Mojeek seems to give less bias results than G or Brave.
