I've had the good fortune to get three job offers. I turned one down because I didn't think it was as good as the others; neither in pay or working conditions. The other two, however, leave us with a difficult decision. One is in the USA, and the other in Norway. They are roughly equivalent in terms of salary versus buying power. It seems that the main advantages and disadvantages are:
USA:
closer to my family (though a couple of states away, so not too close)
farther from Mr. V's family
we can buy a bigger house
only 15 days
Norway
good schools / support for the little ones
no friends or family nearby
good working hours & holiday time
farther from my family, but not too bad for visiting Mr. V's family (UK)
Mr. V slightly favours Norway because of the quality of life. I slightly favour the USA. The job isn't in any states I've lived in before, but it would be a much easier transition for me culturally.
