Great Scandinavaia! But where?

Hello everyone, I am finishing my bachelor and next year am considering making one or two semesters in a university in scandinavia (Norway, Sweden and Denmark) I already know the costs and the requirements, thanks to other students that have visited those countries, but I am not sure which are the best possible universities (My bachelor is for teaching French and English, and in some months I'll get my German degree) and which country give the best opportunities and options for students.

I would appreciate your opinion Thank you for your time
