Don't have access to the published version but draft at https://arxiv.org/pdf/2310.09423 mentions ping RTT at 0.23ms.

As someone frequently at 150ms+ latency for a lot of websites (and semi-frequently 300ms+ for non-geo-distributed websites), in practice with the latency QUIC is easily the best for throughput, HTTP/1.1 with a decent number of parallel connections is a not-that-distant second, and in a remote third is HTTP/2 due to head-of-line-blocking issues if/when a packet goes missing.
