I kind of like PC-BSD's server version a.k.a. TrueOS not so much for its installer but mostly for Warden. However, the fact that ZFS is the only available file system for TrueOS makes it of limited usefulness on anything but enterprise level hardware. And even there due to the well known problems of ZFS with databases it is more or less good only as a storage appliance for non-database files. Almost like a striped down version of FreeNAS.
