The UK is *insanely* good - look at your ISA room. If you can max that for a decade, you'll never pay tax again.
Healthcare is either free at point of use or very very cheap (inc vision/dental, unlike 'progressive' Canada). Stuff is, generally, cheap. The only thing that is expensive is housing, particularly in the South East.
There is a cap gains allowance, a dividend allowance... Lidl, Aldi, and they have made the other supermarkets bring down their prices. Everything except housing is good. Srs.
