The philosophizing on the subject aside, all indications given by the FAA
is that the FSS and DUATS weather and NOTAMS are your only proof should
legal proceedings take place that you followed 91.103.

FSS and DUATS are the only services whose use is supposed to generate
*automatic* proof of the briefing, with no further effort on your part. But
if you get the same information elsewhere, you *may* still be able to prove
that you did so (witnesses, notes, saved or deleted data on your computer,
etc.).
