Answer
Factory methods are more flexible. Frame the concept in practical terms so you can explain it during interview discussion.
Constructors always return a new instance, while factory methods can return pre-existing instances, null, or subclasses. This flexibility allows for more efficient memory use and clearer code. Imagine a factory method returning a cached `Color` instance instead of creating a new one each time.
