Updating rsync through Homebrew vs updating through .tar download

What are some of the advantages and disadvantages of updating the version of rsync installed using Homebrew vs downloading a .tar file and installing it this way https://hargitai.co.nz/upgrade-rsync-on-mac-os-x/

Is what's offered through/from(?) Samba, Github ( https://github.com/rsyncOSX ), and Homebrew (I saw one page describing it as a package manager) all the same program? Or is there some difference (maybe some are forks of others, for example)?

What is Samba from the perspective of a personal computer running OSX?

When you install rsync through HomeBrew an additional patch with a bugfix is applied to the code before it is compiled and installed on your system. You will not (automatically) get this patch when installing manually from a .tar.gz.

HomeBrew also ensures to install dependencies easily. You will have to do that manually when doing it yourself.

Finally HomeBrew makes it easier to uninstall rsync again, if you do not need it anymore.

The software offered on rsync.samba.org and installed in the guide you link is almost identical to the software installed through HomeBrew, except for the extra patch I mentioned.

The software on GitHub you link to is actually not rsync. It is a graphical user interface for rsync, that requires you to have rsync installed in advance.

Regarding Samba: rsync as such does not have anything to do with the software package named "Samba" - so there's no "Samba" involved in running rsync on your personal computer.

The reason why the rsync program is offered through a web site hosted on samba.org is probably just that one of the original creators of the rsync program (Andrew Tridgell) also happens to be original creator of the Samba software package.
