oh boy, where to start...
There are some excellent stuff to be found directly in the bins of Migrosh or Goop.
Aged Gruyere is definitely one - and it comes on sales regularly. Emmenthal - nutty, sweet - is also nice, although I am partial to Gruyere.

Sbrinz is brilliant - not a Parmigiano, although it is comparable to Grana... - and the aged stuff is to behold, but you will rarely find the aged ones at the supermarkets.
For fresh cheeses, I suggest some of the local tommes. Here (Lausanne area) I find some brilliant Tomme Vaudoises - Paudèzes or else - cream, plain, pepper, bear garlic... they are all worth the buy.
