I’m a guy who prefers community based distros. They don’t have business decisions get in the way of the needs of the community. It ain’t perfect, but it’s worth the tradeoffs for me. Debian for stuff I don’t want to constantly mess with. Arch for the express purpose of constantly messing with (and sometimes messing up).
If you can manage a Linux server, you likely have no use for Unraid. If you want to put together a Synology type appliance out of PC hardware to run Docker containers and uses ZFS for backups, Unraid is a fairly user friendly option.
