Hello all! I've been making the switch from American to European tech, and was wondering your thoughts on Vivaldi browser and Qwant search engine.

Vivaldi is based on Chromium and iirc not fully open source, but is still suggested in European tech spaces, and has a pretty good privacy policy.

Qwant is not open source, though claims to not to sell personal data or store searches.

What are your thoughts and perhaps suggestions for alternatives?
