What is the difference between rocket ETH and Lido?

Could you kindly explain the fundamental distinctions between Rocket ETH and Lido? I'm trying to understand the nuances in their functionalities, as well as any potential advantages or disadvantages each might offer. Is there a significant variance in terms of staking mechanisms, returns, or perhaps their security features? Additionally, I'm curious about the communities surrounding these projects and how they might influence the overall experience. Your insights would be greatly appreciated.
