First I choose Ionize because it has good interface and installation was very easy but when I started looking inside the code I saw a big mass. Admin part interface realize with using Mootools as a js framework and MochaUI as a user-interface. So all admin part made by ajax request so I didn't like it because ajax request don't do one big js engine. It happens this way you press link -> js calls ajax request -> it receive big part html with js and change some html that exists with received data. So I stop go forward. Thanks Ionize with it help I watch many information about Mootools and really like plugins.
So after disappointed about Ionize cms I start looking into the code of Halogy cms. It has HMVC patter that I never met (like MVC but groups in folders as modules). So from the beggining it was easy and clear to understand. Code clear and has many comments so I like it. If you want learn CI framework you should look inside this cms.P.S. I think CI is best framework for small websites or for programmers that like writing websites on clear php. For big project I think CI doesn't suitable. CI also gives freedom in writing code, its very easy for beginner, have good documentation, but it has very small functionality versus frameworks like Yii CakePHP...
Вот посмотрел cms 
Как всегда когда рассматриваю чей-то код то пытаюсь понять структуру но когда не получается собираю проект с нуля по частям. Ну и тут так получилось так как cms'ка довольно большая. В общем что не понравилось: Структура (построена на модулях причем вся), Система View ну и остальное. Понравилось только идея с Services очень оригинально, ну и некоторые Ext можно вытащить.
Можно сказать фундамент для cms. Не плохая начальная структура Cms и очень понравилась идея с темами связанных с
