Norway is pretty cool. It's interesting to learn about pre-Kalmar Union Norwegian history, when there were lots of Vikings and warring Kings across the country. Norway has also remained relatively peaceful since World War 2 as far as I know, and it's stayed away from the disaster-waiting-to-happen that is the European Union, which is a good thing. It's also a nice place to visit.
Unlike those two countries, which brutally conquered other countries, made Germans work in mines after WWII as a "punishment," Norway doesn't have that history. They're the best of the Scandinavian countries, aside from Finland. A nice coast, beautiful towns, etc, etc. Norway is my favorite of the countries there for those reasons.
Even though the tax rate of Sweden may be high, they offer premium health care and a very good education system. Sweden also has a great cuisine, beautiful coast, nice towns, etc. Even through it's brutal history, Sweden has rebuilt a well structured economy and a great citizen oriented system.
