• One artefact serves as documentation, visual baseline and interaction test.
• Design-system teams get a shared reference that designers can actually open.
• Rich addon ecosystem for accessibility, viewport and state manipulation.

• Self-contained: spies, clocks and matchers with no extra packages.
• Runs directly in a browser without bundling.
• Extremely stable API — old suites keep working.

• Meaningful configuration and maintenance overhead; a neglected Storybook rots fast.
• Build times on large component libraries get long.
• Stories drift from production usage unless discipline is enforced.

• Feels dated; snapshot testing and modern mocking are absent or bolted on.
• Momentum has moved to Jest and Vitest, including within the Angular ecosystem.
• Weaker TypeScript ergonomics than newer runners.
