I don't mind city life for the most part, except for the whole thing with most apartment complexes being built of cardboard, which means that every single thing your upstairs neighbor and many of the things your adjacent neighbors are doing can be heard loud and clear, and this problem plagues even newer construction. And then you have people on the street yelling, vehicles modified to be as loud as possible driving by, etc.
If these buildings were properly soundproofed, in many ways I'd prefer living in the city, but as things stand the only people who get to enjoy that in cities are those at the tops of skyscrapers renting penthouse suites, all of whom reside in a plane of existence entirely separate from my own.
The number one thing I've enjoyed about suburb life, particularly as a remote worker, is how much more dramatically quiet it is, primarily thanks to not sharing a wall with anybody.
