I'm using DDG a default on my laptop but I end up adding !g in a lot of searches. Google usually finds what DDG doesn't or places it closer to the start of the page.
I mainly keep it as my default because of the "bangs". Which I could configure my browser to do (and did... oh, when did Firefox add that feature? 15 years ago? More?) but setting DDG as my default saves me having to do that. Plus, sometimes, I can get useful ordinary search results without having to look at Google's trashy results page.
