To give you a perspective on Britain since most replies are US centric, I now live close to Shrewsbury near Llangollen on the Welsh border. I've a castle at the end of my road and regularly see (& smell!) cows, horses and sheep from my kitchen window who graze on a paddock where just a few weeks ago I noticed a hot air balloon take off.
My barn has wooden beams, four toilets yet cost less than half to buy than the middle terrace apartment in London that came with 1 toilet and only 1 bedroom and a corridor kitchen. It is also ~4x in area. It came with an allotment and 5 generous plots where I like to plant leeks, onions and runnerbeans where I batch freeze them rather than get them wrapped in plastic shipped from Argentina. I have breathtaking scenery, fresh air and countryside walks nearby along with many ofsted outstanding schools.
It is quite tricky to live far from amenities in the UK so expect markets and farm shops aplenty, I can get unpasteurised milk fresh from pasture grazed cow to bottle the same day which I could not in the city. Our island, being smaller than a state it is easy to get anywhere, festivals are aplenty, fishing in Aberystwyth, a blustery night in Edinburgh for instance and a car or short journey to the station can have you on the continent and in Ghent or Bruge, Antwerp, Berlin or Stockholm the same day.
People are generally rational, courteous and kind mannered. I am greeted as I walk past, unlike in parts of London or Birmingham. I do not lock my doors, and my daughter is learning about life in a safe and idyllic environment I can provide and ok ok it is true my neighbours are mostly old dears, it only means I am less likely to disturb them. I don't hear police sirens and ambulances every day and I don't have to stand armpits in my face travelling the tube yet I can still get to a major airport faster than I when I was in east London for a time.
Unless for the nightlife it beats me why anyone capable would want to be near the cities esp. now with remote work becoming the regular experience of many. If you choose the UK and would like to know more feel free to username -åt- gmail me.
