CodeIgniter Does It For Me

I use CI for it's simplicity.

I have found Laravel a complete PITA to install and configure.

To each his own. My company uses CI but I have also built on laravel. Laravel is FAR more powerful out of the box, but CI is very easy to get going.

Codeigniter is simply one of the tools you need to learn to be a successful developer. Always add more tools to your coding arsenal!
