What each one is
markdown-it
markdown-it is a JavaScript library that converts Markdown text (the lightweight formatting syntax used in READMEs and notes) into HTML. It follows the CommonMark standard for how Markdown should be read, and adds some extras such as URL autolinking and a typographer option. Developers use it when they need to show formatted text on a website or inside a Node.js or browser app.
react-markdown
react-markdown is a React component you give a string of Markdown, and it turns that text into React elements on the page. It avoids dangerouslySetInnerHTML, so it is designed to be safe by default against XSS. You can add plugins to change how Markdown is processed and swap normal HTML tags for your own React components.

Strengths
markdown-it
- Follows the CommonMark spec, which the README describes as 100% supported
- Configurable: you can add new parsing rules or replace existing ones
- Safe by default, according to the README
react-markdown
- Safe by default, with no dangerouslySetInnerHTML needed according to the README
- Lets you replace rendered elements with custom React components
- Supports plugins from the unified ecosystem such as remark-gfm
Not ideal for
markdown-it
- Non-programmers who only want to write Markdown documents; the README describes a code library, not an editor or app
- Projects that do not use JavaScript, since the README only shows npm installation and usage
- Anyone who needs a graphical tool; the README does not describe one
react-markdown
- People who want JavaScript or JSX embedded inside Markdown files; the README points to MDX for that
- Developers who already know unified well and want a hooks-based alternative; the README points to react-remark or rehype-react
- Projects that are not using React
Trade-offs
markdown-it
- The README is short on details about specific features; the full documentation lives on an external site
- Upgrading to v15 involves a migration guide, so version changes may require work
- Plugin quality varies, since plugins are community-written packages on npm
react-markdown
- The package is ESM only, which may need configuration in older build setups
- Async plugins need MarkdownAsync or MarkdownHooks rather than the basic synchronous component
- Full GFM support requires adding a separate plugin
