Use React when you need fine-grained control over the build pipeline and have experienced JavaScript developers who excel with composable architectures. The concurrent renderer introduced in React 19 significantly reduces input latency, making it ideal for high-interaction user interfaces (InfoWorld).

Opt for Angular when your project priorities include long-term maintainability, built-in internationalization, and auditability. The U.S. General Services Administration’s ngx-uswds project demonstrates how Angular can deliver accessible, standards-compliant federal applications right out of the box. Similarly, the UAE Digital Government Maturity Model favors frameworks that enforce consistency across vendors—something Angular enables through schematics and strict typing.

A 2024 Kinsta report noted that while React remains ahead in terms of available junior talent, Angular leads on bundle-size optimization thanks to more effective tree-shaking.

For a simplified comparison, the Appinventors 2025 decision matrix outlines when to choose each framework based on your team and project structure.

In short: Choose React for fast-paced, consumer-facing apps. Choose Angular for enterprise-grade platforms involving multiple teams, compliance needs, and long-term support.
