You're right, as a stand alone chapter, it is the best one since Kabuto's flashback. Fitting in the timeline however.... fuck it.
Also, about the Godzilla level battles... they don't transition that well onto paper, but do transition well onto the tube. If the anime is allowed to continue on, this will be one of the best episodes, fighting-wise (and probably humorous as well... remember ape/pig-faced Yahiko-Pein?).
