FreeBSD is Coherent

One of FreeBSD's biggest strengths in the Open Source operating system arena is that it is a complete, coherent operating system. GNU/Linux is as fragmented as the name; Linux itself is only a kernel, not an operating system. The various distributions are collections of a particular build of kernel along with the GNU utilities and some others conglomerated together, and in Jimbo's personal opinion, the end result often seems pretty arbitrary and incoherent.

FreeBSD is not just a kernel, it's an entire operating system maintained by a group of people called the core committers. This means that both the kernel and the core applications are developed in tandem, and a vision is maintained of "the overall package" and how it works together that is simply not possible with GNU/Linux distributions.
