Overview
The right form model depends on workflow complexity, testability, team conventions, and the stability required in production.
Template-driven forms suit small, simple screens where most behavior lives in the template. Typed reactive forms suit complex workflows, dynamic controls, cross-field rules, and teams that want an explicit testable model. Angular 22 also documents Signal Forms, but they remain experimental, so I would evaluate them behind a deliberate adoption decision rather than presenting them as the automatic production default.
