As someone who has lived in several countries, I do not believe every developed nation achieves better healthcare outcomes than the United States. Many European countries, as well as Canada, offer some form of universal coverage with free general treatment but waiting times for appointments and procedures can vary widely. That said, I still think universal healthcare is preferable, as these systems tend to prioritize urgent cases effectively and ensure that emergency treatment is fully covered for free.

I think, it's only the Asian countries who have got cheap, easy, and effective healthcare where you can not only get appointments quickly but you can get treatment for cheap too but their emergency services are not always as streamlined as those in more developed systems. There is no clear overall winner. Some places excel in certain aspects. Others perform better in different areas.
