I don't think Attic is a good choice anymore; it's unmaintained for ~2
years and has critical data integrity and security bugs. Borg is the
active fork. The Borg team is developing new features while also
triaging the Attic bug tracker, although they've worked through most of
those Attic bugs by now:

I like Borg overall. I've restored from it many times now, and it's
always worked. The developers are actively maintaining and improving the
software, and there is even a commercial offering (rsync.net). It's a
very similar backup paradigm to Tarsnap (snapshots composed of
deduplicated encrypted chunks), although the key management is less
advanced.

I'm not familiar with Duplicity so I can't compare it to Borg.
