I live in Switzerland, and the response here to the virus and most other incidents are far more federally managed than the cantonal system would imply to someone accustomed to US states, in my opinion. If forced at gunpoint to generalize, the simplest explanation I would use having lived in both countries is that in Switzerland the cantons have more independence in execution, while in the US they have more freedom in legislation.
