I suppose that depends on your definitions of "good" and what counts as being "based on performance". For instance QUIC and HTTP/3 support better reliability via things like FEC and connection migration. You can resume a session on a different network (think going from Wi-Fi to cellular or similar) instead of recreating the session and FEC can make the delivery of messages more reliable. At the same time you could argue both of these ultimately just impact performance depending on how you choose to measure them.

Something more agreeably not performance based is the security is better. E.g. more of the conversation is enclosed in encryption at the protocol layer. Whether that's a good reason depends on who you ask though.
