Telesin, current Norwegian collision course with many EU and NATO countries is interesting and unprecedented. Frozen relationship between Hungary or threat of Czech Republic to break up diplomatic relationship with it after it caught its ambassador lying to the Czech media and to the Czech President is unparalleled in modern European history. It does not reflect well on the country that portraits itself as a humanitarian superpower of the Universe. Misunderstanding between two states are common, but they can be explained if there is a good will. Considering that Norway had ignored three diplomatic notes from fellow NATO member country, it shows only its arrogance.
I have been almost every European country from Spain to Finland, from UK to Greece, and Ireland to Russia, so I have my favorites and I can compare. However, considering where Europe as whole is heading, there won't be much worth to visit in the next five to ten years. I used to have family in Vienna since the time of Imperial monarchy. I was there in the 70's, 80's when Iron Curtain was difficult to cross to visit my relatives. They all had passed away, and I do not have much reason to go there anymore. I been in Vienna at least 40x in my life, but this city is dirtier as the years go by. Last time I went there with my spouse we toured places where my aunt and cousins lived, but we got to run down street with full of Muslims and we witnessed a brutal street fight between some Turks. We swore never to visit that city again. If I want to see street adventure, I can go any inner city project in USA without wasting money on travel and exchange rate.
