Comparing HTTP/1 to QUIC is apples to oranges. You would need to compare HTTP/1.1 to HTTP/3. And QUIC to a combination of TCP and TLS. Do you understand those through and through too - or are you just utilizing libraries to make them work? HTTP/3 is actually not super complex. The main trickiness comes from header compression. But unlike HTTP/2 the stateful QPACK compression part in HTTP/3 can actually be deactivated, and just the stateless static dictionary and huffmann compression being used.
