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.

Indeed, I think it's more of a bias on my part. LC-AAC and vorbis (encoded via aoTuV) should give similar results at bitrates above 128kbps, but I have a natural tendency to use vorbis anyway. I don't exactly have a target bitrate, but I'd like an audio encode to be as transparent as practically possible. Dealing with captures, I'd stick with the original encoded track if possible.
