Is Kraken expensive?

I've been hearing a lot about Kraken recently and its role in the cryptocurrency market. Could you please clarify for me if Kraken is considered expensive? I'm trying to understand if its fees and costs are comparable to other major exchanges, or if it stands out as being pricier? Additionally, are there any hidden costs or surprise fees that users might encounter while using Kraken? It would be helpful to get a comprehensive overview of its pricing structure to make an informed decision about whether it's suitable for my trading needs.
