I am starting a new project for a massive fintech platform and I am torn between React and Angular. I know React is a library while Angular is a full-blown framework, but which one offers better long-term maintainability and scalability for a team of 20+ developers? Does the rigorous structure of Angular provide more benefits for large teams compared to React’s flexibility?

For a fintech platform with 20+ developers, Angular is often the safer bet due to its "opinionated" nature. It provides a standardized structure out of the box, including routing, form validation, and HTTP client services. This means every developer on your team will be writing code in a similar way, which is crucial for long-term maintainability. React, while powerful, requires you to choose your own libraries for everything, which can lead to "decision fatigue" and a fragmented codebase if not managed by a very strong lead architect with strict coding standards.
While the structure of Angular is great, doesn't the steep learning curve of TypeScript and RxJS make it harder to onboard new junior developers compared to the relatively simple JSX syntax used in React?
React’s Virtual DOM generally offers faster UI updates for data-heavy dashboards. If your fintech app has lots of real-time price updates, the performance of React might outweigh the structural benefits of Angular.
Actually, Karen, with Angular's "OnPush" change detection strategy, the performance gap has narrowed significantly. Both can handle real-time data efficiently if the state management is architected correctly from the start.
That’s a valid point, Steven. However, for a fintech app, the "hardness" of TypeScript is actually a benefit. It prevents a whole class of runtime errors through strict typing. In React, you usually end up adding TypeScript anyway to handle complex data structures. The initial onboarding might be slower in Angular, but the catch-up time is usually recovered through fewer bugs and easier refactoring once the team is up to speed on the framework's core patterns.
