I've lived both.
I prefer the suburbs.
The endless concrete becomes unbearable after a while. Parks are a refuge, but are seemingly always taken up by organized teams. As a Chicago boy, we went to the parks as much as possible, but were still getting kicked out by baseball leagues in the day, and softball in the evening. I hated not having a creek to play in and find frogs.
As an adult, the 6 or 8 inches of wall was no barrier to roaches, bedbugs, parties, rough sex sounds, etc. My suburban yard is.
The key to the yard is learning low maintenance. Here people are planting grass that needs cutting maybe every 4 weeks, or in many cases, just groundcover. The grass yards are usually for people with kids. The groundcover versions or for the rest of us.
Can I walk to a store? Yes. It takes 30 minutes. It is a long walk. It is good for me. It is not 5 minutes like Chicago. Oh well.
