Lol I saw that one, it was hilarious. The Swedes legimiately doesn't care for us that much for some reason (obviously generalising). Might be because we can understand them and they can't understand us, as in basically they are jealous. We also find the Swedes a little effeminate sometimes and their prices on alcholol are way too high. I've lived on the island Amager, which is part of outer Copenhagen, all my life and at a certain point I lived near the harbor. Swedes during summer not being able to handle their alcohol was a thing. The Norwegian tend to like Swedes better than us as well, mainly because again they don't understand us and we understand them perfectly fine, as well as both Sweden and Norway being neighbors and having similar landscapes. Denmark is basically entirely flat.
Long story short, Denmark is the best country. Less isolated, understand all Scandinavian languages, less snobby, cheaper alcohol, warmer weather, better banter. Not nearly as beautiful landscapes and nature though.
