Framework popularity is a poor reason to pick the core of a client system. The better question is whether the choice fits the product, the team's skills, and the years after launch.
Begin with the constraints
We look at the existing stack, expected traffic, security needs, integrations, and who will maintain the result. A content-led site may benefit from a familiar CMS. An application with complex workflows may need a more tailored backend. A small product rarely needs several languages and deployment platforms to solve one problem.
Compare the cost of ownership
Development speed matters, but so do upgrades, hosting, hiring, monitoring, and dependency health. We look for mature tools with clear documentation and a path to keep them current. A newer tool can still be right when it solves a real constraint; the reason should be written down.
Avoid a stack that only its authors understand
Keep the architecture as simple as the requirements allow. Use standard project setup, automated tests for risky paths, and a deploy process another engineer can follow. When a specialized component is necessary, isolate it and explain its purpose.
Technology should give the client options. A good decision remains understandable when the original team is no longer in the room.
