Free version does not have all the features. If you want all the features, you will have to order for Professional version that supports all the features what they written in their website. Free version has very much limited availability.
But for advanced developers, you will agree to purchase Professional version as because you wanted do some real time works.
Their user interface is very much normal. Would like to see advance development and better UI design.
They have lightweight and speed fast IDE which supports HTML, CSS, PHP, MySQL facilities with Version controlling and FTP features. Also have popular framework supports which will give you snippets to work more fast.
They are best in their place as because they supports web development features with extra framework plugin like, Laravel, Yii, CakePHP, CodeIgniter, WordPress, Drupal, jQuery etc. This is the one tool that supports all the things.
By using this tools, they are very much lightweight. Speed, Reliable, Fast and good debugging facility. Although support version controlling system and FTP access as well.
