Under the part about Hyper-V isolated containers: You should continue to use Windows Server as the host for production deployments. By using this feature on Windows 10 Pro and Enterprise, you must also ensure that your host and container version tags match, otherwise the container may fail to start or exhibit undefined behavior.` https://docs.microsoft.com/en-us/virtualization/windowscontainers/manage-containers/hyperv-container#hyper-v-isolation It's not for testing but for deployment. With part of the file system on server, the quicker start up and above warning I'd say the answer is correct.

Why are none of you (with the exception of KidCastaldo) focusing on the unique file system requirements? Windows Containers don't do that. Hyper-V containers do.

Windows Containers and 3 "Windows Server containers offer greater density and performance for when speed is key, such as lower spin-up time and faster runtime performance compared to nested configurations." https://docs.microsoft.com/en-us/virtualization/windowscontainers/about/faq

This all boils down to the requirement of a unique file system. Windows containers do start faster yes, but do they have their own unique file system? Windows Containers share the Hosts OS Kernel. Hyper V Containers have their own complete OS and Kernel. Because of the requirement to have a unique file system I am leaning toward Hyper V Containers https://docs.microsoft.com/en-us/virtualization/windowscontainers/about/ https://searchservervirtualization.techtarget.com/tip/Windows-Server-containers-and-Hyper-V-containers-explained
