If you call "headache-free" an easier setup, then you're about right, there's will be a handful of solutions out there to satisfy you.
IMHO, "headache-free" NAS OS is something that will never exist; or you have some workload in the beginning with a more complicated setup, or you will buy a pre-customized product that will be easier to setup, but may lead to catastrophic loss with the usage of non-friendly SOHO storage system, because RAID5/6/Z are enterprise-focused on data availability and integrity, not on data resilience. Windows, by far, is not suited to the task, I'm afraid.
Maybe LT could make things easier by creating some "wizard" setup that asks where the user want to store it's downloads, it's movies and it's documents, and the docker system request the predefined value instead of letting the user choose every path. But this didn't take the merits of the product itself.
