I've visited most of Europe, some countries like England, France, Spain, Italy, Germany, Czech Republic, Latvia - many times. Plus, I've been to most of the Eastern block (Belarus, Ukraine, Russia).
I can tell you with a good amount of certainty that they all are somewhat different. But they are all not ideal. I was very disappointed by England and France, due to thousands of migrants from middle East and Africa. There were moments when I thought that I am in an Arabic city, somewhere in Libya or Egypt. Eastern block is, on average, poorer and more chaotic. So dunno. This is my 4th month in US, there are some things that I really don't like about the country (cultural mostly, I don't like the food here, and the women... Nothing to compare with Eastern Europe), but there are many great things that I missed in my country.
Trading something for something you will definitely lose something. Are you sure the opportunity cost is worth it?
P.S. If you'd move to Europe, I'd suggest Austria or Denmark
