Which is better, Agile or spiral?

Neither Agile nor Spiral is inherently "better"; they are suited for different project types: Agile excels in dynamic environments needing fast, flexible delivery with frequent customer feedback (e.g., web apps), prioritizing working software and adaptation, while the Spiral Model is ideal for large, complex projects with high risk and uncertainty, focusing on systematic risk management through iterative cycles. Agile offers high flexibility and customer collaboration, whereas Spiral provides structured risk mitigation but with less continuous client involvement and more upfront analysis.

This ensures a steady flow of work, prevents the backlog from becoming overwhelming, and balances immediate needs with future product vision, promoting efficient backlog refinement.
