How much does Rocketpool take?

Could you please elaborate on the matter of Rocketpool's fees? I'm interested in understanding the specific breakdown of their charges. Is there a set fee structure or does it vary depending on the nature of transactions or staking services? Additionally, how does Rocketpool justify its fees compared to other staking pools in the market? I'm keen to know if these fees are competitive and worthwhile considering Rocketpool's offerings.
