Hm... this is a really hard question for me, honestly.
I should like the UK better, for most of the reasons people have mentioned; better transport, historical/cultural interest, food & drink, free healthcare (important for me as I have chronic conditions), political values closer to my own. Plus, of course, there's the whole part where I get to be with my husband. That's kind of a big deal.
The problem is that the particular corner of the U.K. that we live in just has almost none of those advantages, but does have some of the disadvantages that Bluegrass Lass mentioned (i.e. sectarianism). Combined with the utter lack of any job opportunities, I have to say that, if I could take my husband and dog with me, I'd move back to the U.S.
Though, I have to admit, I'd move just about anywhere else in the U.K., too. It's just that, in our situation, moving to Inverness would be just about as complicated as moving back to Wisconsin.
