I'm a little confused as to what the actual milestone is here? "We got 13% faster vs our last build" is just... well.. every day. I thought there was going to be some specific metric that they beat. It's good that browsers get faster at specific benchmarks, but what we basically always see is that the web gets more complex whilst browsers get faster (this is just an extension of the effect where software gets more complex as hardware gets faster and therefore the software you're using at any given time basically stays the same speed).
However, and I think this is important to bring up, browsers are basically the same speed and the reason to use one over the other is largely down to ergonomics and larger concerns. On the "larger concerns" side, Chrome is a failure. Chrome exists so the advertising company Google can track you and sell you targetted ads. It can do this in reasonable ways and it can do this in unreasonable ways, and with attacks on privacy like FLoC. Chrome is doing exactly what Internet Explorer was doing for microsoft in the 2000s and I think it's appropriate to call out that fact.
