The public spaces seem better maintained than in the USA. Mass transit is also better in general to equivalent American cities. A lot of it feels driven by a relative lack of homelessness in tourist areas combined with continued post war investment in urban areas.
Food seems more expensive in general, but it depends on the country/region.
I’ve never had to deal with EU healthcare besides Covid testing. Turkey is really great for medical tourism.
Europe felt safe in general, but then I feel safe in where I travel in the USA.
