FuelPHP vs PHP-MVC: What are the differences?

Developers describe FuelPHP as "A fast, lightweight, community driven PHP5 framework". FuelPHP is a fast, lightweight PHP 5.4 framework. In an age where frameworks are a dime a dozen, We believe that FuelPHP will stand out in the crowd. It will do this by combining all the things you love about the great frameworks out there, while getting rid of the bad. On the other hand, PHP-MVC is detailed as "Simple and easy to understand MVC skeleton application". This project is - by intention - NOT a full framework, it's a bare-bone structure, written in purely native PHP ! The php-mvc skeleton tries to be the extremely slimmed down opposite of big frameworks like Zend2, Symfony or Laravel.

FuelPHP and PHP-MVC can be categorized as "Frameworks (Full Stack)" tools.

FuelPHP and PHP-MVC are both open source tools. It seems that PHP-MVC with 1.25K GitHub stars and 494 forks on GitHub has more adoption than FuelPHP with 284 GitHub stars and 57 GitHub forks.
