To be clear, I'm the original author and primary maintainer of
pgBackRest. I'll let the Barman folks speak to their strengths, but I'm
happy to address your points below.

This a good feature, and one that has been requested for pgBackRest. You
can do this fairly trivially with ssh, however, so it generally hasn't
been a big deal for people. Is there a particular reason you need this
feature?

Another good feature. We have not added it yet because pgBackRest was
originally written for very high-volume clusters (100K+ WAL per day) and
our parallel async feature answers that need much better. We recommend
a replicated standby for more update-to-date data.
Even so, we are looking at adding support for replication slots to
pgBackRest. We are considering a hybrid scheme that will use
replication to keep the WAL archive as up to date as possible, while
doing bulk transfer with archive_command.

I'll stick with some of the major pgBackRest pros:
- Parallel backup including compression and checksums
- Encryption
- S3 support
- Parallel archive
- Delta restore
- Page checksum validation
- Backup resume

pgBackRest is used in some very demanding environments and we are
constantly answering the needs of our users with features and
performance improvements, e.g. the enormous improvements to archive-push
speed in the 2.0 release.
I'd be happy to answer any specific questions you have about pgBackRest.
