The models' case: The de facto default for new React apps in 2026 — copy-in components you own outright, built on accessible headless primitives (Radix/Base UI) + Tailwind, with a huge. The models' main caveat: Not a versioned dependency — no upstream upgrades, so every copied component becomes code your team must maintain and patch. The strongest alternative is MUI — Most complete production ecosystem, with superb documentation, mature theming, accessibility work, and exceptional data-grid and date-picker options. Not unanimous: ChatGPT picks Mantine.
