Copenhagen airport is my favourite too - note however that Arlanda T5 is being expanded at the moment and it seems like it will be a lot nicer when they're finished. The security stuff is already much better: no need to unpack laptops etc. from hand luggage when going through the new section. T2 is still quite sucky though!
