 From my experience, the source upgrade is more failsafe than the
binary upgrade. If in doubt, I always use the source upgrade.  IMHO
you don't need to do anything special, just follow the instructions in
/usr/src/Makefile, and don't forget the delete-old step.

The mergemaster utility is also much more convenient than
freebsd-update's merge routine, and you can rerun it as many times as
you wish provided you have backed up your original /etc. I have always
wondered if I could somehow use mergemaster together with binary upgrades.

The last problem I had with freebsd-update (AFAIK when upgrading from
9.x to 10.x) was that after the first "freebsd-update install && reboot"
all my network interfaces were gone: the old ifconfig did not go well
with the new kernel. Luckily I had console access. I don't know
however if this would have happened in case of a source upgrade.
