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

RAD Studio

  • Professional edition costs $2,000 for the perpetual license plus $599 for year one maintenance, totaling $2,599 before tax
  • Enterprise edition steps up to $3,400 license plus $1,199 maintenance, and Architect edition to $4,416 license plus $2,183 maintenance
  • The perpetual license only entitles the buyer to updates for one year; continued access to new updates and upgrades requires an annually renewable Update Subscription
