Which is better, Play Framework or Spring MVC? How should I decide what to use?

Spring is the best choice for enterprise-level web apps with serverless, microservice-based and/or event-driven architecture, as well as apps with high-security requirements and/or asynchronous code; Spring Boot will be useful in stand-alone app development and for building production-ready Spring apps.

Spring MVC is widely adopted, offering extensive features, flexibility, and strong community support, making it ideal for enterprise-level applications. It's mature, with a vast ecosystem but has a steeper learning curve. Play Framework is more developer-friendly, with rapid development capabilities, built-in reactive programming, and hot-reload features, making it great for high-performance, scalable web apps. Choose Spring MVC for complex, large-scale enterprise projects requiring extensive integration and robustness. Opt for Play Framework if you prioritize speed, scalability, and developer productivity, especially in projects needing reactive, non-blocking architecture. Your choice depends on project requirements, team expertise, and long-term goals.
