Using Kagi is not a bad decision. After reading a lot of positive things about it and beeing quite hyped, I was so ungently reminded, that every good thing comes with its own baggage of bad.
I thought I share it, so that everyone can make their own decision.
I also tried Metager, a german meta search engine. Sad to report: not usable for me, although I like their club (suma-ev) and donated some money towards them.
