I've used borg for a while and like it a lot. I would say your best option for pure linux is borg+borgmatic/vorta just because borg is battle-tested.

If you run any other OSs and don't mind a relative newcomer, I've found kopia to be easy to recommend to my windows friends. At this point kopia has been around long enough (~4 years?) that I think it's safe to trust its integrity with personal data. It has all the important features from borg in a cross-platform solution, so it's also a viable alternative for borg on linux if you don't like borg's frontends for whatever reason.
