It's an engine vs. a car comparison: while pg_basebackup is useful as a stand alone binary, a database deployment need multiple backups. To manage multiple backups you need a catalog. You also may want optimize the backup process, so instead of multiple pg_basebackup, you want some logic to copy only changed files.

Also, when restoring, it's important choose a restore point, and a tool to help on that is valuable.

This is the first time that I heard of this tool, I need to check all features. I know both barman and pgbackrest, so if someone wants to compare with other tools, those 2 worth a look.
