I hope to open the doors to discussion with this question. I am a CodeIgniter developer looking for an E-commerce solution that follows a similar MVC structure like CI. I have narrowed it down to two solutions, but maybe someone knows of something better.
Magento - really well done, but slow Opencart - takes advantage of MVC, similar to CodeIgniter in coding style, quick, but doesn't use a clean URL structure
So, my question is, what is the best PHP E-commerce solution that takes advantage of MVC, is similar to CI, is fast, robust and open source?
