Metager (https://metager.de) looks neat, seems to have proper results and is backed by a public charity.

Indeed! MetaGer's international version has improved recently, too: https://metager.org/
Both DDG and MetaGer use Yahoo/Bing and Yandex as their main sources, so results are very similar.
MetaGer is now experimenting with adding Yacy and Searx as sources. This might even add Google results via Searx.
@c Highly unscientific, but I *think* I am getting results about as good as from DDG, so I might actually switch to it as my default search engine. 🙂
