IMO The EFF test is very flawed because it only tests your uniqueness among the other visitors to that site, not the total possible uniqueness from all the bits of data.

I would bet money that Brave cannot defeat CreepJS. The only thing I've ever seen do it, ironically, is Safari in private mode.

Also just using your computer normally and visiting regular websites already tracks you regardless of your browser's privacy abilities, and I promise data brokers don't care what browser you use, your overall online behavior is still unique.
