It is superior to CentOS in a lot of ways:
- A lot less delay releasing (rebuilding) RHEL updates compared with CentOS (specially important for security updates)
- Free to use and distribute like CentOS
- You have access to optional support
- You can install UEK that has BTRFS and a unlocks a whole new kernel generation to RHEL base
It was better than CentOS for years. You can switch from CentOS with a script that updates your repos and that's it.
And second: CentOS Stream is not that bad ideia. Why way to long for fixes/updates? It is and will continue to be slow, just not super-slow.
