I live in Winterthur with my family since 9 years, and we are very happy.
We don't have a car ... everything can easily be reached by bicycle, and Zürich is easy to reach by train ... 30 minutes.
Everybody goes shopping in Konstanz, Germany.
Switzerland has many giant secondhand shops, over here they are called Brockenstube or short: Brocki. Sell your stuff and buy second hand over here. https://m.youtube.com/watch?v=chlQ9giYzbA
Welcome to Winterthur! Be prepared for tropical heat during summer!
