I honestly don't know. The best if to check for yourself. I guess it's
still in general worse than vorbis (I haven't tried myself, but older
blind tests said that FAAC was worse), but _maybe_ in the cases where
vorbis screws, FAAC doesn't screw as much.

But I have never tried FAAC, so just don't trust me on that :)

Reinventing the wheel certainly is annoying, but as long as all other
wheels are square...
