I've done a lot of research and testing with Markdown, Asciidoc, and reStructuredText to see which would work best for my company's documentation needs. We ended up going with Asciidoc and Antora for the following reasons.
Asciidoc:
* Almost as simple as Markdown.
* Less convoluted than reStructuredText.
* Excellent support for complex tables, captions, callouts, etc.
* We prefer Asciidocs table structure to Markdown's since it is easier to create and maintain.
* Excellent documentation.
Antora:
* Comes with a default template, which makes building prototypes easier.
* Ability to pull from multiple git repositories.
* Native Asciidoc support.
* Fast compile times.
* Good documentation.
Based on our research, I even migrated my personal 11ty sites from Markdown to Asciidoc and have been quite happy with it.
