The only situations where I use those RHEL clones is pretty much to support the customers who do want to run RHEL but are too cheap to provide proper build, test,... environments with licensing too.

The actual huge benefits come from early adopter distros since those are the ones finding the bugs that more "stable" distros then don't have to deal with.

For actual production use something that isn't quite bleeding edge but also isn't too far behind to get the benefits from new features and still supported upstream versions (e.g. like Debian stable during the full support phase) is much better than the 10 year LTS distros like RHEL.
