Norwegian here, can confirm. I can speak to Swedes pretty easily with them in Swedish and I in Norwegian. Danes, despite the fact our languages are written about the same, are really hard to understand in speech. It's much easier to just switch to English. Going further, I've found that the mainstream Swedish dialect is probably more mutually intelligible with the mainstream Norwegian dialect than some of the more obscure regional Norwegian dialects (and I say this as someone who grew up speaking one of those regional dialects).
