The short version

Each has a real cost: Bacula the community edition has no vendor support contract; bacula.org directs support and paid deployments toward the separate commercial Bacula Enterprise product instead.; Kopia space is only reclaimed when maintenance runs, and in a shared repository full maintenance is owned by one client, so if that machine goes away the repository grows for ever while every backup still reports success.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Bacula

The community edition has no vendor support contract; bacula.org directs support and paid deployments toward the separate commercial Bacula Enterprise product instead.

Kopia

Space is only reclaimed when maintenance runs, and in a shared repository full maintenance is owned by one client, so if that machine goes away the repository grows for ever while every backup still reports success.
The repository format has changed across versions and mixing client versions against one repository is discouraged, so a fleet must be upgraded together rather than machine by machine.
There is no central orchestration or reporting for many machines, so monitoring a fleet means building your own alerting around exit codes.
Restoring many small files is slower than the backup was, because content must be reassembled from pack blobs, and this is rarely tested until the day it matters.
Encryption is client side with no escrow, so a lost repository password means the data is unrecoverable and there is no vendor to appeal to.

Answered from the vendors’ own pages

Bacula: How much does Bacula cost?

Bacula Community Edition is free and open source. Bacula Enterprise is a commercial offering with a free trial available, but specific pricing is not listed on the main website.

Source

Kopia: Is a partly corrupt repository still restorable?

Partly. Deduplication means one damaged pack blob affects every snapshot referencing its contents, but unaffected files still restore. Run verification regularly rather than assuming.

Bacula: Is Bacula free?

Bacula Community Edition is fully free and open source. Enterprise Edition is commercial but offers a free trial to evaluate features before purchasing.

Source

Kopia: How does it compare with restic?

Similar guarantees, with packing that behaves better on per operation billing, a desktop interface, and compression enabled by default.

Kopia: Do I need to run maintenance manually?

It is scheduled automatically by default, but you must ensure the client that owns full maintenance keeps running, otherwise deleted snapshots never free space.

Kopia: Can several machines share one repository?

Yes, and that is where deduplication pays off, but they should run compatible versions and only one owns full maintenance.
