It's totally different country by country. I never been to the US, but I imagine it's much more homogeneous than the EU. For example you can go to Berlin, Barcelona, Milano, Stockholm or Budapest and you can have radically different experiences. It differs radically financially, demographically and attitude wise.
I'd suggest to start with a Euro-trip and visit as many countries as you can and then make a "final" choice where to settle.
