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

Notion AI

  • Full AI access including agents and meeting notes requires the Business plan at $20 per member per month, double the $10 Plus plan
  • The Free and Plus plans offer trial AI capabilities rather than the full feature set
  • AI is not sold separately from the workspace seat, so every member must be upgraded to reach it
  • Zero data retention with LLM providers is Enterprise only, which is custom priced
