I grew up in countryside but live in cities as an adult.
Pros:
Peace and quiet, green, nature, cleaner air.
Usually bigger garden so more chance to grow things at home.
Often local suppliers including farm gate honesty boxes
Usually space for storage etc incl outdoor space
Easier to get to green space
Cons:
Lack of public transport or limited options (which may not include early morning or late nights)
Smaller local shops and a need to travel further for a big supermarket
Could have limited/no local options for coffee shop, cafe, nice restaurants (but there could be good, just limited number of, options available)
Need a car
Need to think ahead more for bad weather etc (should do in city also but less critical)
Living in the country, we had open fires with a log shed we filled every summer, and depended on a gas tank for central heating so had to arrange for it to be filled.
We were more used to potential power cuts etc so had proper supplies always on hand and ways to cope with no electricity etc.
We were used to being organised about shopping - my parents went to the local city weekly for the big shop and mostly got milk and meat in local butcher, paper shop and veg from local grower. But would always have at least a spare box of pasta, 1 unopened bag of flour, few tins etc. And would build up certain things before winter. They also had a big pantry and a full sized chest freezer (sometimes bought half a cow in 1 go, or put in gluts of summer veg from garden for winter use etc).
Also tended to be more self sufficient generally - repairing clothes and stuff as not always easy to replace in a hurry, having to plan on replacements or new season clothes etc as part of shopping trips rather than just popping into town. Or having more spares at home in advance.
Any family that had a car, DCs all learned as soon as they were 17 whereas many in city don't bother until much later.
But DCs in city can be more independent at earlier age as there is transport available.
If I had the option, I would live in the countryside but keep my car. And many of the problems when I was young are far less now as streaming means you catch up on movies earlier, online shopping works far better and there is much more choice, ebooks are available instead of waiting to get to library/occasional bookshop visits etc.
