I might b a little bias, but I think you will find the attitude of the people in Norway more on the pessimistic side of things.
For example:
You say to a Norwegian; "beautiful day isn't it". His likely reply will be "but it will be rainy and windy tomorrow".
Swedes, stoic as they can be, are a little more cheery.
Go visit both Countries if you can afford it. Plan your own itinerary, and rent a car, no need for an over-priced tour where they will just herd you around to the most expensive tourist shops and restaurants. Everyone in those Counties speaks English, probably better than you and me.
The State Department has a system they use to rank the difficulty of foreign languages for staff like ambassadors, embassy personnel, etc... to learn to speak.
If I remember correctly, Norwegian is the easiest language for English speakers to learn.
If the Normans had decided to stay home (or were defeated) in 1066 it would probably be even easier to speak any of the Scandinavian/German languages today.
