I am aware you're probably saying this because you're German and the Swiss are German speaking (among other languages)-
However I recently visited my friends in Zurich (they are French) and they indicated to me a level of Xenophobia I had not expected from such an advanced country.
Obviously a few bad apples spoil the bunch in this regard but some of the tales they told were not only shocking (such as selective enforcement of the law in favour of Swiss) but also horrifying (such as people openly insulting them in retail stores).
Obviously I was just visiting and did not experience anything such as this, but I take them seriously.
This was also corroborated with an IRC friend of mine who happens to be Swiss.
Obviously I'm not trying to inform your opinion, but I would be remissed if I didn't mention it given that it's specifically listed as a relocation option.
