Interesting ! My comparison was indeed limited, I only lived in center of Den Haag as a foreigner. Decentralization has its pros and cons, but Paris is way too centralized around Chatelet sometimes.

France as a whole is way too centralized on Paris and it's actually hurting the country. If you do read French, there is a very interesting book from 2024 (IIRC) about this. It's called "Quand le parisianisme écrase la France".

Before reading this book I always thought Germany (where I grew up) was the exception for being more decentralized. But it looks like actually France is way more centralized even compared to other pretty centralized countries.
