This is a difficult question, because none of us know you and have any real idea of what would ultimately work for YOU. Contrary to the common opinion, pilots are not all the same, and we don't all want the same things. You might be just as miserable at a US legacy as another person may be at EK. It sounds like you're already living in that general part of the world, so Dubai may be less of a culture shock to you than to some. I'm not sure if you've lived in the US before. If not, there is no telling how you'll respond to the American environment. You might love it or you might not. I WILL say that bank account balance is not everything. None of us can take it to the grave, so...
I guess what I'm trying to say (awkwardly, I might add) is that the only one who can truly answer that question is you.
