Intriguing question, OP!

My opinion, if you've not traveled much, you're better off staying in the US. There is still a wide variety of choices here. Adjusting to another language and culture can be way more difficult than anticipated.

Also, an American traveling to other countries for the first time may be shocked by the difference in plumbing standards and ready availability of hot water. Most of us Americans really don't know how good we have it.

That said, do all the research, then listen to your gut. Go wherever it guides you. You are embarking on a great adventure. Enjoy every second.

Best of luck to you! You seem like a smart, able person who knows what he wants. I have no doubt you'll find it.
