Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
MUI
- Escaping the Material Design look takes more theming effort than teams expect
- Bundle size is significant, and careless imports pull in far more than needed
- Advanced components such as the full data grid require a paid licence
- Major version upgrades have historically required real migration work
Sphinx
- reStructuredText is harder to write than Markdown and puts off contributors, though MyST now allows Markdown
- Configuration is complex and the default output is dated-looking without theme work
- Build times on large documentation sets are slow
- Heavier than the problem for a small project that only needs a few pages

Answered from the vendors’ own pages
MUI: Is MUI free?
The core library is open source and free. Advanced components, including the full-featured data grid, require a paid licence.
Sphinx: Is Sphinx free?
Yes, open source under the BSD licence.
MUI: Can MUI look non-Material?
Yes, through the theming system, but a substantial departure takes real work. Teams wanting full design control often prefer unstyled primitives instead.
Sphinx: Do I have to write reStructuredText?
Not any more. The MyST extension allows Markdown, though reStructuredText remains the native format and most examples use it.
MUI: Does MUI handle accessibility?
Components follow WAI-ARIA patterns by default, which is a large part of why teams adopt it.
Sphinx: Why do large projects choose Sphinx?
Automatic cross-referencing and API extraction from docstrings, which lighter generators do not provide.
