Not much time, I’ll be brief with three examples that come to mind from my experience:

Great use: Large filestorage with regular changes, daily snapshots, stream snapshots offsite as backup.

Not so great use: Storage backend for qcow2 backed VMs on spinning RAID. CoW made a mess of access times.

Really not great use: Large Postgres-DB with queries that creted large ondisk temp tables.

It really depends.
