Ease of use and stability is what I liked most about CIS RHEL. RHEL7 installation on virtual machines were a breeze, and with RHEL7, I didn't see any hiccups or issues with the OS installation. It is a good option for new users or companies that requires a secure OS for mission critical workloads. The benefits include low cost per seat, lower maintenance on servers, availability of security updates. Installation was straightforward and the support is available for almost all the questions and queries. I feel that it is the best RHEL version for enterprises. CIS is one of the most trusted and reliable Linux distribution vendors with their products, having certified and tested on various workloads available for Linux and Windows. With CIS, I am confident of maintaining a secure environment for my customers. I like that it's a very secure operating system, it's very reliable. It's easy to use. It has all of the tools you need for any kind of server. It is compatible with other linux distributions. The only downside is that it can be difficult to install some applications. You have to know what you're doing when installing software. It's a great OS for servers. I use it for my work as a web developer.
