Germany, not even comparable lol.
Affordable healthcare, clean living spaces, decent wages for the majority of people. Also, Mississippi has the highest gun death rate in the US.. Not sure how much feeling safe should factor into QoL for you but that's a pretty significant one in my book
I have lived in Germany for five years and your parent poster is right. Scandinavian countries and The Netherlands are generally better. But Germany is a great country to live in with high living standards.
