RST at a glance
RST
Convert to RST when the content is headed into Sphinx or another documentation system that benefits from directive-rich plain text.
It is well suited to API docs, developer manuals, internal technical references, and documentation that needs cross-references, notes, code blocks, and publish-time transformations.
Use it when documentation semantics are more important than office-style page layout.
DOCX at a glance
DOCX
Convert to DOCX when the document will keep evolving after export.
It is the right target for contracts under review, proposals with tracked changes, policy drafts, editable reports, and documents that recipients are expected to open in Word or Word-compatible editors.
Choose DOCX when comments, revision history, page layout, headers, footers, and embedded assets need to remain editable.
If the goal is fixed presentation or print fidelity, PDF is usually better; DOCX is for collaborative editing and office workflow compatibility.
