It also depends upon the operating system among several other variables,
I didn't find noticeable difference between FF and Chrome based browsers(Vivaldi, Edge) on macOS(although Safari runs circles around them) after using them extensively. I used each of them for a separate project with several common websites loaded in them, there were different quirks for each browser(especially reg tab hibernation) but latency was not one of them.
On Linux FF seems definitely faster than Chromium, although there are occasional DNS errors which stops loading the web pages altogether(likely result of my own doing). I've stopped having different browsers for different projects and just use FF for all.
On Android with Chrome, not just Chrome but even WebView using it is astonishingly fast(e.g. DDG browser), I presume it's because of data saver feature. On de-googled android like LineageOS, FF/Fennec seems to be on same level as Chromium and DDG is faster here as well.
On iOS, everything is Safari.
I don't use Windows much, but I've seen others mentioning Edge seems to be faster than Chrome recently.
