I do, and I don't find it too bad. I switched from DDG back to Google recently because I realised I had to use !g on most of my searches.
I stopped using Google for web search, but I still use it for Google search.
I do see the Google info box style results, but I find these to be one of the most useful parts and it's one of the reasons I like using Google for things that are basic facts, media fact finding (like "who was that person in that show" style queries), etc.
I only use google search on my phone because I have a pixel, and the google searchbar is so well integrated into the launcher. If I don't like the results, I can just open a new tab and the default search is DuckDuckGo. Besides the ads, I'd say the searches are usually the same quality.
