Which is better, agile or waterfall?

Neither Agile nor Waterfall is universally "better"; the choice depends on the project: Waterfall suits projects with fixed, clear requirements (like building a bridge), offering structure, upfront planning, and predictable costs, while Agile excels with flexible, evolving needs (like software development), providing rapid feedback, adaptability, and continuous delivery through iterative sprints. Agile is favored for innovation and customer involvement, while Waterfall provides control for stable, well-defined projects, with some suggesting hybrid approaches for complex work.
