Hi Nun,
I've just moved back to the UK after 12yrs in California, I've brought my US hubby and since arriving have given birth to our first child a daughter, Hope Lavender. We had the huge house on a hill, with the big SUV's and lots of nice material stuff. We have moved however to a smaller house, car, no sunshine and so far so good. The UK allows me to stay at home with our daughter with no worries, my hubby also gets lots of time off work to spend with us. The UK is way more family friendly and the medical is free, a huge bonus for us. Taxes are however higher so there is a trade off.
Good Luck!
