Configuration needs tweaking...
The default settings you get when installing it does not help, and you typically need to make sure you have configure 0-rtt and that your congestion window size is set correctly, not a lot but essential, and for that you remove almost all the overhead from TLS/HTTPS rountips for setting up encryption, and that you don't need to pause and wait for congestion protocols in the middle of an average size document you sen/receive.
So why not use UDP - UDP have no relaibility, the QUIC protocol adds that without additional coding, just like TCP does.
In short, you can easily win 200-600ms while having zero downside from lossy UDP.
