Are Kraken fees high?

I've been hearing a lot about Kraken recently, and I'm considering using their services for my crypto transactions. However, one thing that's been holding me back is the question of fees. Are Kraken's fees high compared to other crypto exchanges? I understand that fees can vary depending on the type of transaction and the amount involved, but I'd like to get a general sense of what I might be looking at. Are there any hidden costs or surcharges that I should be aware of? And finally, are there any ways to reduce or avoid these fees, perhaps through loyalty programs or volume discounts? I'd appreciate any information you can provide to help me make a more informed decision.
