Depends on your use case for me I use Unraid for my "production" home storage for 3 main reasons 1. It is easy to administer I dont want to have screw with it when I just want to watch a movie from my emby server, or get some file I am working on 2. It allows me to disparate disk sizes, and expand the storage at will. Something TrueNAS and other ZFS based system struggle with 3. The Docker interface is the easiest I have ever found I want the "one click" service experience for my home services server. I do not want a package manager, or to ssh in to the server and start doing things. That said i also run 2 other Storage servers that are TrueNAS, I use them for backups, and doing the things you talk about. However with TrueNAS I have to plan out my Storage like I would my enterprise arrays, a 5 year storage plan, and preallocate the space when I build the array, because expanding it after the fact is a pain in the a*. (an no I am not going to keep adding mirror pair vdev's) That is the key here, use the correct tool for the job, and for a production server to run "home services" like emby, plex, gitea, paperless, SAMBA shares, Home Assistant, etc nothing IMO beats unraid, not even TrueNAS
