Quick Answer
Template-driven: uses directives (ngModel), form logic in template, async validation is complex, less testable, less code for simple cases. Reactive: FormGroup/FormControl in TypeScript, validators are plain functions, dynamic form fields with FormArray, unit-testable without the DOM. Reactive is preferred for any form with complex validation, conditional fields, or dynamic structure.
Answer
Template-driven forms rely on template directives and implicit data flow. Reactive forms use explicit FormControl objects, enabling predictable state, dynamic validation, and easier testing.
