What I like the best about MAMP is the convenience of the application. Setting up a local PHP/MySQL test server with a WordPress installation is a breeze. Working with MAMP on my Mac for building websites locally saves me time to get started with the building side of development.

Its easier to use different PHP version for different projects.

MAMP saves me a lot of time providing me with a one click solution to have PHP, MYSQL, APACHE, PEARL, RUBY, NGINX and SSL certificates running on my Mac. No more tedious command line installs... say goodbye to homebrew.
