Start with the interface you need to build. A mostly static publication, an interactive dashboard, and a real-time collaboration tool have very different requirements. Write those constraints down before comparing tools.
What matters in practice
Evaluate the team as carefully as the technology. Familiarity reduces delivery risk, while a smaller ecosystem can increase the cost of hiring, debugging, and long-term upgrades. Build one representative feature before committing.
A useful rule
Prefer boring evidence: release cadence, migration documentation, accessibility defaults, bundle output, testability, and the number of dependencies required for common work. The best framework is the one your team can still understand and update two years later.
