I’m currently trying to decide between Borg and Restic myself. Borg has worked very well for me in the past, and I’m a bit excited by the new Vorta GUI frontend. But I already have a BackBlaze B2 setup for backing up my Mac, and Restic would let me continue to use that as a backup store. I’m interested in hearing about differentiating points between them.
Primarily it's the reason you already know: restic and borg are the same model, but restic doesn't need it to be an ssh-accessible filesystem on the remote end. Restic can send backups almost anywhere, including object storage like your Backblaze B2 (that's what I use with restic, too). I agree with OP: restic is strictly better. There's no reason to use borg today; restic is a superset of its functionality.
