The models' case: Best overall reliability, cross-browser coverage, auto-waiting, resilient locators, parallelism, tracing, network control, and first-class TypeScript tooling. The models' main caveat: Reduce browser-binary overhead and version coupling. The strongest alternative is Cypress — Outstanding developer experience, interactive debugging, time-travel snapshots, component testing, network stubbing, and polished cloud analytics.
