DDG is a more practical default than Google simply because I don't get a "We'd like to abuse your personal data" pop-up that gets in the way every time I open an Incognito window to search for something.
Sadly I have found the DDG lacking, most times I have to go back to Google to find information that just doesn't show up on DDG. As an example, I don't have Twitter but I follow certain sport journalist with a huge following, all thanks to his Twitter. When I search for his name + twitter, DDG shows me articles about the journalist and even a Facebook page link, but not his twitter even if it is in the query and his…
But yes, I do use !g when needed to jump to Google. It's just the default that works better on DDG for me due to the Incognito window issue - so much so that I've been running DDG by default for quite a long time now, just for that reason.
