If you're learning the language, it's just so much easier to do it here.
Other than that, I prefer just about everything about living here compared to living in the states: people are kinder, children are treated better, the food is healther and tastes better, religion is less important, people are not nearly as outwardly angry, discussions about politics, religion, etc. can go on without people losing their shit, etc. etc.
I think it's one of the freer places I've experienced, and I recommend it to anyone willing to learn a language and not have a life exactly like that which you experience in your birth-farm.
