In case the OP wanted to know exactly how Brave's adblock is different from uBlock Origin instead of a link to the marketing page with links to other things like cryptocurrencies:
Brave's browser claims a speedup over AdBlock plus, but was inspired by UBO, so the performance is fairly similar, but is baked into the browser instead of being an extension.
> We therefore rebuilt our ad-blocker taking inspiration from uBlock Origin and Ghostery’s ad-blocker approach.
