The RFCs are more stable. The bis drafts are officially works in
progress and therefore are subject to change. Developers hate coding
to a spec that is a moving target (on the other hand, they hate coding
to a spec that will soon be obsolete, too).
Yes, although the bis drafts are subject to change, they are almost
certainly normatively closer than the RFCs to the final bis documents.
IMHO that fact, plus all the clarifications, corrections and
improvements, makes them better for developers.
