I had the impression that in the beginning Borg started as a fork of Restic to add missing features, but Restic was the more mature project.
Is there still anything Borg has that Restic lacks?
For me the reason to use Borg over Restic has always been that it was _much_ faster due to using a server-side daemon that could filter/compress things. The downside being you can’t use something like S3 as storage (but services like Borgbase or Hetzner Storage Boxes support Borg).
That’s probably changed with the server backend, but with the same downside.
I am very much in the market for a replacement (looking at Rustic for example).
