In the pre-APFS days, there was one difference in that using time machine would give you snapshots whereas CCC would only be a "dest like source" backup (safetynet would preserve deleted files, but not version modified ones). You could work around this with ZFS snapshots on the destination, but since it's not natively supported it's all a bit clunky. With APFS you get snapshots too, so the only real difference is the UI for restoring a snapshot.
I do wish Apple would allow 3rd party applications to populate "versions", so the inbuilt UI could be used with other apps. It could even fit with their existing Finder extensions: it could bring together different versions of a file on cloud providers, local backups, etc., and present them in a unified UI.
