I like that they have several different options for us when it comes time to install or configure an appliance server such as SCCM2012 (our current version).
We also appreciate them being able to support multiple versions at once so we can try out new features without having too many clients impacted by any issues! Not much else really - just be prepared if you plan ahead about how long your implementation will take because there are often unexpected delays from other projects within Microsoft's schedule which may result in longer than expected project duration. Implementing Windows Server 2012 R2 Enterprise into one location across all client devices was challenging but OCG made sure everything ran smoothly including configuration changes/updates after rollout!
