I have actually completed my Physical Therapy education in the Netherlands. I've done 2 internships there, one in a private practice and a second one in a hospital. I enjoyed the private practice a lot because my supervisors were very helpful while the supervisor that I had in the hospital was pretty rude. The language was a barrier often since I don't speak Dutch. However English is spoken by so many in the Netherlands that you will definitely get patients who click with you.
I don't have any experience in the US so I could not compare, sorry. I would recommend doing a rotation in another country just for the challenge and uncertainty of it!
