How would you personally rank the following Swiss cities from most to least tourist appeal?

Hi, I'll be visiting Switzerland in August, staying in Interlaken for around 7-8 days, then Zurich for 2-3 days. Besides these 2 cities, and Lucerne (which I've heard is Switzerland's most picturesque city), which of the following do you think I should prioritize?

- Bern

- Geneva

- Basel

- Lausanne

- Montreux

- St Galo

Any other recommendation is appreciated, this will be my first time visiting the country and I'd like to do 50% nature, 50% cities and towns. Thanks
