I switched to DDG mostly, and nowadays its results are great for most cases. Imo Google is a habit to break.
it's great if I know what I want to search (i.e. I know the field and the keywords and I need the specifics) but when I don't know what I want to search I can't use it for discovery (i.e. when learning new things and I lack the terminology)
The bangs are painfully slow over the main duckduckgo site.
Miss the bangs.
Also, for non-trivial results, Qwant is mostly a fancy Bing front-end, so you might as well use Bing.
