Use **useState** when:
- Managing simple, independent state
- State updates are straightforward
- Component has 2-3 state variables
Use **useReducer** when:
- Managing complex state with multiple sub-values
- Next state depends on previous state
- State updates involve complex logic
- You need to dispatch actions from different places
For a complex form, useReducer is often cleaner!
