Firefox + Ghostery vs Brave Browser
Just tried brave browser on Linux.
Brave: Version 0.65.121 Chromium: 75.0.3770.100 (Official Build) (64-bit)
FireFox: Version 67.0.4 Ghostery 8.3.4
Linux: Ubuntu: 19.04 with kernel 5.1.3-050103-generic
On the sites I tried, Firefox was faster and more trackers were blocked (less requests were made).
Love Rust though.
