OK, just tried Epic Privacy Browser and here are my findings
1) It's a fork of Chromium(open source) but not being audited. Anyway, who has officially audited each and every line of codes in open source programs like Chromium, Firefox, LibreOffice etc.?
2) It uses ENCRYPTED proxy which is faster than if I don't use it
3) No DNS leakage.
However, it leaks your IP address even with encrypted proxy turned on
4) It has its own web store but only a handful of extensions. Brave has no web store for now.
5) It's fast and you can access the chrome flags. No Appcontainer flag. Brave browser don't allow access to its chrome flags.
6) Cannot add extensions besides those found in its web store. Brave browser does not support extensions for now.
7) It's now at v58.xxx....one version behind stable Chromium. Chromium forks(like Cent, Iridium, SRWare Iron etc) are similarly so. Brave keeps same pace as stable Chromium.
8) On start up it connects to Digital Ocean(ISP) in Netherlands. On startup Chromium and its forks(like Cent, Iridium, SRWare Iron etc) connect to Google whilst Brave connects to Amazon
9) Supports 3 plugins(Chromium PDF Viewer, Native Client and Adobe Flash Player) which can be disabled if you don't like them
10) Cannot change search engine unlike Brave
11) Very minimal user settings
12) It auto updates on its own
13) It's an Indian company
I would suggest using Adguard for Desktop and Sandboxie if you want to run Epic and Brave browsers
Not much info on the net. Found
