What is the difference between Coinbase and Coinbase pro?

Could you elaborate on the key differences between Coinbase and Coinbase Pro? I'm particularly interested in understanding the user interface, trading fees, available cryptocurrencies, and any additional features that set them apart. For instance, is one more suitable for beginners while the other caters to experienced traders? Additionally, how do the security measures compare, and what are the limitations or advantages of each platform? Understanding these nuances would help me decide which platform is best suited for my trading needs.
