As I said in another comment, I still expect TCP to use fewer cycles than QUIC due to kernel optimizations and partial NIC offload. IIRC people have done benchmarks showing this. Saturating 10G or even 100G with either protocol should be easy enough these days but if you want to do 400G or more from a single server then it matters.
