Should you always use design patterns?

A design pattern provides a general reusable solution for the common problems that occur in software design. By using design patterns, you can make your code more flexible, reusable, and maintainable. Its not mandatory to always implement design patterns in your project.

What is the most appropriate GoF pattern to use?

Factory design pattern is most suitable when complex object creation steps are involved. To ensure that these steps are centralized and not exposed to composing classes. Abstract factory pattern is used whenever we need another level of abstraction over a group of factories created using factory pattern.
