I have no idea why they (whoever made that infomatic) are comparing Brave to Chrome because Brave uses Chromium code. All it is is Chromium with a few built-in privacy extensions. Brave is also owned by an advertising company, which is already sort of a red flag. They also pay people to spam advertise their company, which is why you see Brave everywhere.
Firefox is eons better for privacy. It already blocks stuff and it isn't based on Chromium. I don't know why Brave makes it seem like "other browsers are based on Chromium" because this isn't the case. I also don't believe it's degoogled Chromium either, so there may still be Google source code sending stuff back to Google - please let me know if I'm wrong.
Coupled with extensions like uBlock, Privacy Badger, HTTPS everywhere, nano blocker, potentially a script blocker, and a proxy, and you are home free.
