Having lived in both Germany and the US, my experience with the German system is that there are a lot more, smaller hospitals and private practices, the care is good, and all I ever paid for out of pocket was prescription medications. I didn't have to wait long for an MRI (two weeks) versus months in the US. I had a number of things that would have been hundreds or thousands of dollars in the US that I never paid a penny for in Germany. I'll also say that hospitals are absolutely crazy about sending bill collectors after you. I had a handful of small charges--like $10 or $20 things--that I hadn't realized were even there and two months later they freaking inundated me with bill collector notices.

It does make a big difference exactly where you are in the US, however. Some places have a glut of healthcare providers and other places don't.
