1. I use it on a NAS system. For years this was vanilla FreeBSD from 10 to 13. A few months back I replaced the system with TrueNAS Core which is based on FreeBSD 13, retaining the ZFS pools from the original installation. This system hosts storage and network shares, services hosted in jails such as databases, build slaves and artefact storage, and Windows virtual machines also hosting services and remote desktops.

2. First-class ZFS support, full NFSv4 ACL support which works with Samba and Windows ACLs and is a massive improvement upon POSIX.1e DRAFT ACLs.

3. No real preference, but ZFS support is (for me) the killer feature. Next are jails and Bhyve.

4. The main lack is the more comprehensive selection of drivers found on Linux. That said, it's pretty decent and I do find the overall quality of the drivers and system as a whole is better than Linux.

5. The system is engineered as a cohesive whole. While other BSDs might be similar, and perhaps Debian was attempting this a couple of decades back with its core design principles, most of the alternatives are lacking in this essential cohesiveness.
