If Brave is running circles around Chrome for you in general, that's likely a result of cognitive bias, since last I checked it's the same rendering engine.
For pageloads Brave might do better if it blocks various stuff by default, of course.

This is one of the key differentiating factors of Brave. Maybe next time don’t lead with accusations of cognitive bias.
I am quite aware of what Brave's value proposition is. Generally when people are only talking about pageload performance they say so, because there are many other performance metrics relevant to web browsers, some of which are arguably more important for most users...
I recently switched to Brave Developer Edition [1], which now supports Chrome extensions (which I need for work/pleasure). It runs circles around Firefox and Chrome, and maintains my privacy better.
Previously it was a tradeoff of getting speed (Chrome) or maintaining privacy (Firefox). For me, Brave does better on both counts, and now that it supports extensions I'm completely sold.
