Technical differences between lossy codecs

What are the major technical differences between MP3, AAC, WMA and Vorbis? They are all transform codecs, the only specific thing I know that MP3 has a hybrid filterbank instead of straight MDCT as with the other formats. Yet, all of them give different artifacts with low bitrates.

AAC, WMA and Vorbis are all vaguely similar transform codecs, although each is implemented quite differently.  The wikipedia pages for each have some information that I've written up over the years, but your best bet is to look at the decoder source.
