Question Ranking
Pros

Intuitive and easy to use web gui.
Pro Mult-environment cluster system
- Cattle (Rancher default)
- Swarm
- Kubernetes
- Mesos
Pro Service catalog is easy
Rancher provides a catalog of application templates that make it easy to deploy complex stacks.
- Rancher certified catalog
- Community service catalog
Pro Self-service application stack for self-monitoring
Great contributions from the co community who build the service stack catalog.
One of them is the "Prometheus" template which deploys a collection of containers for monitoring a platform. It's capable of querying all aspects of your environment with some nice pre-built dashboards.
Pro Access control polices
Detailed role-based access control policies can be defined independently for each cluster.
Pro Small learning curve
Learning to use OpenShift is pretty easy. Most environments can be set up in a few simple steps and for everything else the official documentation and third-party resources are extremely helpful.
Pro Built-in continuous integration
Continuous integration is not only built-in OpenShift, it's actually a standard part the workflow.
Pro Can be used to introduce specialized tasks through the application hosted on it
Because of its high flexibility and customization power, OpenShift can be used to create specialized tasks for the application being hosted on it. For example, an entire array of dynos (also known as gears) can be dedicated to media transcoding in order to build a custom media converter infrastructure.
Cons
Con Official customer support is lacking
OpenShift seems to rely more on written documentation and on the community to solve any problem users may have. The forums and IRC channel are active and very helpful, but the official customer support could be better.
