Deploying QUIC led to substantial p95 and p99 latency improvements when I did it (admittedly a long time ago) in some widely used mobile apps. At first we had to correct our analysis for connection success rate because so many previously failing connections now succeeded slowly. It's a material benefit over networks with packet loss and/or high latency. An individual human trying to accomplish something in an elevator, parking garage, or crowded venue will care about a connection being faster with a greater likelihood of success.
