What is the difference between Coinbase and Robinhood?

Could you elaborate on the key distinctions between Coinbase and Robinhood in the realm of cryptocurrency and finance? Both platforms seem to offer trading services, but I'm curious about the specific differences in terms of user experience, fees, available cryptocurrencies, and the security measures they implement. Does one offer more flexibility in terms of storage and withdrawal options? How do their interfaces differ, and which one might be more suitable for beginners or advanced traders? Additionally, I'd like to understand the regulatory aspects and any compliance measures these platforms adhere to in various jurisdictions.
