The power of CentOS was long term support of 10 years and that it is completely Open Source. That's what afaik no other free Distro delivers and thats why RedHat upset so many people. With virtualization and containers it doesn't even matter that CentOS is behind, when it comes to new versions or even bleeding edge software. So Centos is just about a stable platform with long term support.I have seen some new users on OmniOS (OpenSource Solar is fork) coming from Centos as this is a ultra minimalistic, easy to maintain and very stable base for a server especially when services like ZFS, iSCSI, NFS and SMB/AD is the main use case. There is a stable, a long term stable and a commercial support option, OmniOS Community Edition
Only AlmaLinux as of now brings exactly this to the table.
