I like Swiss. The semi-dry kind with lots of little holes.

That is all.
"Swiss" as can be found in the US has /nothing/ to do with the real stuff. OTOH, I did find a nice Comté (basically as close to real swiss cheese you can get in France; it comes from the part of France that is very close to Geneva) at Whole Foods in Las Vegas last year.
Then, of course, you have to consider that Switzerland is not one country, but a federation of cheese. Every Kanton (state) has to have its own. My three favourites are Gruyère, Appenzeller and Emmentaler, in that order.
And, to circle back; when I first went to the UK on my own time back in 2012 (all earlier trips were hysterical ones for work or as very young with my parents, certainly pre-dating the W & G moon trip) finding and tasting Wensleydale was a priority.
Still, the swedish Westerbotten cheese is /very/ hard to beat.
/Måns, whose fridge contains Westerbotten, Prästost, Saint-Agur, and a _very_, _very_ aged Dutch Gouda.
