Is MetaMask safer than KuCoin?

Could you please elaborate on the safety comparison between MetaMask and KuCoin? I'm curious to know which one offers more robust security measures. MetaMask, as a wallet, seems to have a strong reputation in the crypto space, but KuCoin, as an exchange platform, also claims to have stringent security protocols. Could you provide some insights into their respective security features, including encryption techniques, two-factor authentication options, and any past security breaches, if any? Additionally, how do they handle user funds and private keys, and what steps do they take to safeguard them? It would be great if you could offer a comprehensive comparison to help me make an informed decision.
