What is the difference between Coinbase and Nexo?

Could you please elaborate on the distinctive features of Coinbase and Nexo? I'm particularly interested in understanding their differences in terms of security measures, the range of cryptocurrencies they offer, their user interfaces, and any distinct advantages or disadvantages they might have. How do their fee structures compare? Also, it would be helpful to know about any unique services or features that each platform provides that sets it apart from the other. Thank you for clarifying these points for me.
