SunSpider is a JavaScript benchmark, probably one of the oldest ones around. We ran version 1.0.2, the latest and last version released (SunSpider is no longer maintained).
For this benchmark, a lower number is better.

Firefox did a lot worse:
Edge managed to slip right underneath Chrome:
Brave did a bit worse than the other Chromium browsers, but better than Firefox:
This is an old test, so it shouldn’t be taken on its own.
