How does this differ from what is provided by SCTP?

SCTP doesn't work on Windows and doesn't pass through NATs. You could layer TLS over SCTP but QUIC has integrated always-on crypto and anti-ossification protection. The SCTP four-way handshake is presumably slower than TCP while QUIC supports 0-RTT mode.
