Well, Molde & Ålesund are west, not north ;) Tromsø is proper north and very different from Molde/Ålesund. There's a lot more culture there, as well as being the right place for sitting in a fjord and watching northern lights. I know people who have moved there temporarily and really liked it.

But it's definitely the case that whilst the Scandinavian lifestyle often features as best life satisfaction/happiest/whatever, it's definitely down to personal preference. These countries also tend to score low on happiness/life satisfaction for immigrants, which shows that the benefits are only perceived/received by some.
