I've been using ZFS for the past 3 years without any major issues. For my server, all my media is stored on a group of HDDs in an external HDD enclosure using RAIDz2. I currently use Proxmox, since I wanted a stable OS and it has support for ZFS baked-in.
My personal laptop has root on ZFS, running Arch. ZFS is a kernel module installed separately in this case. Since Arch is a rolling distro and I like messing around with it, I appreciate running a FS with snapshots where I can easily rollback when something breaks. Plus, ZFS supports native encryption!
