Comparison Moodle - Chamilo

I need a comparison between two learning management systems: Moodle and Chamilo. Need to cover (at least) - market penetration, and features. I will give some guidance regarding our needs around LMS, describe the environment where the LMS will be used and what is important for us. Urgency is more important than detail, so I will want a highlevel result in a day or two. This may be follows by more work to get more details, but if needed I will post this separately. This bid is for what can be done over a day or two, so if you are already familiar with one of apps (or both!) that would be great.
