But I have noticed no differences between either. So I kind of prefer having the AUR version when available. It is to my understanding on the how to install brave on linux faq on braves official website it suggests to use the brave bin file for Manjaro.

In addition for whatever reason, the official repo version always lists the build as unknown like how yours shows that after (official build) and the brave bin from AUR shows it as just official build. This constant switching between brave versions is the only way I can stay up to date. By switching back to that more recent version then next thing you know the AUR version shows a later more recent update days later. For whatever reason when I decide to update lets say from the AUR brave bin next thing you know a few days later or even the next day the official repo version all of the sudden has a later update available.

I say remotely updated because for whatever reason Manjaro is always days behind on updates in comparison to windows brave updates or even ubuntu. Not sure if this is relevant, but as a fellow Manjaro user I must say the only way I have found to keep brave remotely updated is to switch between brave bin located in AUR and the brave official repos.
