Flymix,
having worked both sides of the atlantic, pro's and con's to both sides as you would expect. Although I would wager that half way through your CAA licence validation, you'll be totally fed up.
Should be worth it in the long run as Uk terms/conditions much superior and work reasonably plentiful at the moment.
Quality of life depends largely on your priority's. Good vacation, time off, pay (compared to states) and a national health service, but you'll have to pay the earth to live in a shoebox, surrounded by too many people, way too much traffic and pay the government most of your money back in taxes.
The government here sucks, they're all greedy B**d's, who only look after themselves first. So no difference to the states there then! And whilst that's getting off topic slightly, that does effect your quality of life.
Anyway best of luck.
