I enjoyed it when I used it! I moved off of GNOME about a year ago, though, and it doesn't work as well outside that ecosystem, so I switched to Vorta, another Borg client (Borg is the underlying backup software). Just recently, I switched to borgmatic.
@benjaminhollon That's one of things I really like about Pika Backup.
Since it uses such a popular backend, you can switch to another client without losing anything.
