What is the strongest currency in Scandinavia?

Could you please clarify for me which currency is currently considered the strongest among the Scandinavian countries? Is it the Norwegian krone, the Swedish krona, or perhaps the Danish krone? I'm curious to know which one holds the most value and stability in the region, and how it compares to other global currencies. Additionally, what factors contribute to its strength, such as economic stability, political climate, or trade relations? Thank you for your insights.
