Depends on the context with which you are arguing, I suppose. In this case it might have been more correct to argue FreeBSD vs. Debian. I still stress, though, that the difference is still a notable one; even though Debian may be a tight and clean distribution it's still considered "GNU/Linux" - FreeBSD is just FreeBSD. The BSD's do have some cross pollination but they aren't united under a single umbrella as all the distributions of GNU/Linux are. Debian is sort of stepping away from this by building a distribution that matches GNU user land with the FreeBSD kernel. I haven't personally used Debian that much, so I can't reliably argue for or against it (but I've heard good things); my arguments generally stem from my lovely experiences with FreeBSD and my generally frustrating experiences with GNU/Linux (no new argument here, everything I said in this sentence is said in my above post).
