There is evidence that FreeBSD is a better platform for NTP than Linux;
I'm not certain that evidence is conclusive, but certainly FreeBSD with
a current 4.2.x NTP distribution seems to work very well. One advantage
of FreeBSD is that it supports kernel time discipline if you want that,
while Linux kernels 2.6.x don't (there were patches for kernel support
for 2.4.x, but they didn't carry forward).
I'm running a couple of 1U servers with Celeron 433 processors and
FreeBSD, and they seem to work very well.
Your mileage may vary...
