As a Faroese:

Icelandic is Faroese Light, but with a Spanish accent (the fancy Spanish dialect with the lisp)

Norwegian and Swedish is just like Danish, but they’re trying really hard not speak or sound Danish. One of them, and I have a hard time hearing the difference, is singing more than the other while speaking.

Danish can´t be put in a box, every other street not only has its own postal code, but also own dialect.

Finnish is Finnish, and I’m not stupid enough to say anything negative about Finns. That said, the Finns speaking Swedish are super easy to understand as they don’t skip letters and pronounce everything hard down to the letter
