What extensions does Brave functionality replicate

I tend to install extra extensions in Brave, like Privacy Badger, uBlock Origins, and Windows Defender Browser Protection. I know that Brave already replicates HTTPS Everywhere, but what does Brave do on it’s own? What extensions do I not really need?

Conversely, what extensions are helpful to double up on? Is there any harm in keeping Privacy Badger or uBlock Origin, for example? Are there things I should add to maintain a reasonable level of privacy?

Personally, I’m not looking to have to tweak uMatrix or the like. I’m just looking for a little extra protection.
