Red Hat Insights gives a lot of insights into known issues that you do not think about unless you call support. It tells you to proactively go fix this or do this.

The most valuable feature of Red Hat Enterprise Linux is the Ansible Automation Platform, closely followed by Satellite. These two tools are integral to our environment.

The testing of the updates or the packages of the kernel is valuable because I used to be a part of the Fedora project. I know it is all vetted out before it gets to production, but a majority of it is the support and the relationships I have with the Red Hat employees assigned to our account.

The biggest differences between Red Hat Enterprise Linux and the other OS' are the support, Satellite, Insights, and the fact that Ansible was acquired by Red Hat so you can use all its automation and toolings. The entire ecosystem works very well together.
