Hello Pheefoohoing76
Your question cannot be answered as such; it is not specific enough.
It is like asking us: should I eat Spaghetti or Pizza?, while we do not know whether you like the one or the other 🙂
You have to tell us what you are planning to do in Switzerland, as it makes a huge difference where you will be staying and what your plans are.
Also, 3 days mean: 3 full days, or 1 full day in Switzerland?
Kind regards,
Roland
