USA: best opportunities for smart people to engage in big-impact work. People are too crazy about work. Depending on the city, can also be unsafe. Switzerland: extremely high financial compensation but also high cost of living despite low taxation. People love nature but many are too materialistic. UK: Was the most interesting country to live in up to 2016, no sadly going isolationist. Germany: good quality of life but a bit boring apart from a few hip cities like Berlin or Cologne.
Although the weather there sucks, living in Edinburgh, Scotland, has been fantastic experience, and it tops all other places. The only disadvantage is that due to Brexit (most Scots were and are against it) it is (now) outside of the EU.
The fact that all EU citizens have complete freedom of movement is priceless (to me).
