There are many, many cities and villages that are only accessible by regional buses. I doubt the residents would consider the train networks to be "better".
...and my perspective may be both local and outdated. Intercity coaches were actually illegal here in Germany until 5 years ago or so, intended to protect the train services (and, I guess, roads and the environment).
Hah! That’s what I thought until I wanted to go to Liechtenstein. You would think Vaduz as capital would have a rail station, but I had to take a bus.
The neighbouring settlement, Schaan, is larger, has all the industry, and has the railway and two stations.
Train is actually my preferred way to travel (that or driving. But it depends where I’m going and why).
