Dude,
I have also lived in KSA, from the late 80s. Now I am in Dubai. The UAE is much easier to live in from certain perspectives. It is hard to save money here, especially as an FO at any of the carriers. Your progression to command will influence your decision here. Good schools are very expensive, not covered completely by any packages that I know of. Lots of expats make the decision to school their kids where it's cheap. This is highly personal, admittedly. Read as much as you can on this site. There's lots of truth in the various rants, more truth than myth. Good luck.
