Which European country has the best education?

Im a student from Taiwan and I'm considering to have a student exchange to one of the following countries:
Spain, FInalnd, Sweden, Norway, Denmark, Austria, and Switzerland.

Are there a particular difference between these countries, since I'm not very familiar with them. Or are they pretty much similar. I'm also a little worried that the courses they might have there will be really really rigerous, is that true?

I would also like to know whether there are AP courses there and what kind of clubs are available. Thanks!
I'm talking about high school
