Which is better, Copilot or Gemini?

I'm curious to know, when it comes to cryptocurrency exchanges, which platform do you think is superior: Copilot or Gemini? Both have their own unique features and offerings, but I'm interested in hearing your expert opinion on which one provides a more seamless, secure, and user-friendly experience for traders and investors. What sets one apart from the other in terms of fees, security measures, and the range of cryptocurrencies available for trading?
