I'm Norwegian with Finnish relatives and I don't see much difference imo. Finland has better candy though, and they have easier access to the sauna. Norway have plenty of mountains and bad weather, and Norwegians are probably more conservative than Finns, atleast that's my impression knowing both sides.
From my understanding its like Austria, Lichtenstein, Switzerland and Germany up there. They are pretty much the same but if you say that they kill you.
It is very much the same and we know it. Still though we're quite elitist and Norwegians will obviously think we're better than the Finns (and everyone else for that matter). And likewise with a Finn, they know that they're the best there is.
