ZFS on FreeBSD is quite nice. System tools like freebsd-update integrate well. UFS continues to work as well, and may be more appropriate for some use cases where ZFS isn't a good fit, copy on write is sometimes very expensive. Afaik, the FreeBSD position is both ZFS and UFS are fully supported and neither is secondary to the other; the installer asks what you want from ZFS, UFS, Manual (with a menu based tool), or Shell and you do whatever; in that order, so maybe a slight preferance towards ZFS.
