UA: Game play vise the ability is uninspiring. It fits the viking theme decently and it's nice to see a exploration heavy embarking ability to fit with the exploration of Iceland, Greenland (Nuuk is a city under its Danish name) and North America. The pillaging bonus is also a must.
UU: The Berserkers are the stereotypical Norse warriors (when they're not high on shrooms, or maybe especially when they're tripping) and are widely reported on in the Icelandic sagas and other sources. While in game it bores you to tears it fits thematically as a brutal viking.
I would love some more Iceland representation. But I really disagree that the UA is uninspiring - I always play totally differently with Denmark. Despite its weakness for overall gameplay it's perfect for what it's supposed to do - like taking unguarded cities with a team of five Berserkers before the AI's army can even get there.
Even into the Atomic Era you can take any city within 5 tiles of the sea in a couple turns, usually pillaging every tile as you go. You can take cities without fighting armies. The coastal raider theme seems perfectly executed to me.
