From a practical standpoint I see little reason to use Vorbis. Usually, my target bitrate for stereo audio is 96-128 kbps. Vorbis is not substantially better than AAC in that range, and if I'm making an mp4 I have to use AAC regardless. For low bitrates, HE-AAC performs better than Vorbis. Also, most of the surround files I come across are AAC or AC3, and reencoding them hurts the audio quality too much. Vorbis is attractive because it is open source with no strings attached, but AAC encoding and decoding support is strong and unlikely to vanish anytime soon.

YMMV.
