I really like Codeigniter because it runs fast and is easy to implement. It provides an easy way of linking to third-party functionality like PHPExcel, Kint, Mustache, and others.
Moreover, it is easy to learn and is a very good framework for PHP MVC development. Review collected by and hosted on G2.com.
