Percona talk about these tools on their website / blogs. Basically, this thing is for logical backup, where you might want to eg only restore a single table. Logical also compresses much better. Innobackupex binary full restore will still be much faster though.
Ever since I started using mysql replication I've been mostly relying on replicated incremental backups with xtrabackup.
To workaround the downside of not being able to restore a single table I'm using some scripts I found online that perform automatic restore tests of the xtrabackup backups with docker. That way I can access the restored DB in the docker container and export/dump whatever I want.
This also enables me to run a restore test and data integrity test on the restored data every day and report the status to my monitoring platform.
