- They diverge on capability: Antora covers Multi-repository sourcing, Read the Docs covers Build on commit.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Antora
- Content must be AsciiDoc, so an existing markdown documentation set has to be converted before you can evaluate the tool properly.
- The component, version and module model must be understood before anything builds, and the first working site typically takes days rather than the afternoon a markdown generator needs.
- Theming means building a separate UI bundle with Handlebars templates and its own pipeline, which is a front-end project most documentation teams are not staffed for.
- There is no search included, so every deployment adds either a Lunr extension with its own index size limits or a paid hosted search service.
- Builds fetch from every configured repository, so large multi-component sites become slow and depend on git availability during every documentation build.
Read the Docs
- Build configuration is finicky, and build failures on dependency changes are a common frustration
- Default themes are recognisable and dated, so sites look alike unless customised
- Private documentation requires a paid business plan
- Build times on large projects are slow enough to interrupt a review cycle

Answered from the vendors’ own pages
Antora: Can I use markdown with Antora?
Not as the primary format. Antora is an AsciiDoc pipeline, and treating markdown as a first-class input means a different tool.
Read the Docs: Is Read the Docs free?
Free for open-source public projects. Private documentation requires a paid business plan.
Antora: Is it worth it for a single product with one version?
Usually not. The model pays off when you have several repositories or several supported versions; below that a simpler generator will do the same job with far less setup.
Read the Docs: What does it build from?
Most commonly Sphinx or MkDocs sources kept in your repository.
Antora: How does versioning actually work?
Each branch or tag of a source repository becomes a version of that component. You publish a new version by branching, not by copying a directory.
Read the Docs: How does versioning work?
It maps branches and tags to documentation versions, so several releases are served side by side without manual work.
Antora: Who maintains it?
OpenDevise, the group behind Asciidoctor, under the Mozilla Public Licence. Paid consulting and custom UI work are available from them separately.
