Pbs is very good at what it does. Deduplicaton is great. You can restore images or files, Easier then veeams file restore appliance imho. Live restore works great. And a user on pve can not delete the backups if you set it up right. You can easily replicate the datastore to a offsite. The backups are very fast for running vm's with qemu' dirty block tracking.
But...
There is no application aware in pbs itself. You need to hook into qemu-guest-agent fsfreeze if you want to prepare oracle for backups. Can find scripts on github.
And there is no DR replication that uses the dirty block tracking to do a short replication to a ready vm. I have scripted a simple restore after backup to have a dr vm ready to start but it is not compareable to veeam dr replication. This is on proxmox roadmap tho, so hopefully soon.
