Qwant is infamous in France for having made big claims and failed repeatedly. It was for the longest time just a wrapper around Bing, while claiming otherwise.
That isn't the case, the engine is quite capable. Have been using for 10 years as replacement for google. Only stopped recently because any AI is now better at answering most technical questions.
It is certainly more private than Google and capable enough to answer my daily questions. For me it is important to reduce as much as possible the entrapment from google services.
