I found [1] which describes the architectural difference between MPTCP and QUIC, and also introduces the authors' proposed MPQUIC protocol: > QUIC multiplexes application streams on a single UDP ﬂow, whereas MPTCP splits a single stream on multiple TCP subﬂows. MPQUIC combines both features by multiplex- ing application streams on multiple UDP subﬂows. [1]: "Multipath QUIC: A Deployable Multipath Transport Protocol" https://www.researchgate.net/publication/327122884_Multipath_QUIC_A_Deployable_Multipath_Transport_Protocol https://www.researchgate.net/publication/327122884_Multipath... Now I'm curious about how these protocols compare in production operation. Anybody have experience with both?

Note that MPQUIC is still being discussed at the IETF. At the last IETF meeting, more changes have been discussed. Unfortunately, that slows down its adoption. https://lwn.net/Articles/964377/ https://lwn.net/Articles/964377/ But both tries to achieve the same goal. Technically, you can have a very similar behaviour. MPTCP is implemented in the Linux kernel, while QUIC is on the userspace side.
