The Asciidoctor flavour of AsciiDoc doesn't have a specification. There is only a working group. The parsers are a mess composed of regular expressions.
There are in effect two different versions of AsciiDoc, because Asciidoctor people have appropriated the name while making their own changes to it and marking what they dislike as deprecated.
AsciiDoc cannot express all of DocBook, for example figures with multiple images.
While I despise Markdown, there isn't all that much to be a fanboy of. Just the syntax is overall saner.
