Well... from experience, there are points where FreeBSD has strong
advantages.  Memory management is an obvious one.  NFS is is another.
Softupdates (the native file system) also has a small edge.  We run a
linux binary on a FreeBSD cluster (100-or-so nodes) because the
FreeBSD cluster will do about 5% more work than the exact same
hardware booted with linux (we actually use a diskless DHCP boot ---
so we can quickly swap back and forth to test).

5% isn't a huge difference, but it is a real world application.
