Definatly
CPH.
I'm not saying it because I'm danish. But like CFM-56 already said. There is more to see at the airport in
CPH and it's much closer to the heart of
CPH.
If you want to take the train to Copenhagen city from the airport it's only about 4$ and if you want to take the train from
ARN to Stockholm the price is about 30$. So there is a big difference there for sure.
Edit: Both cities are very beautiful and offers alot to do and see. But go for CPH.
