So after some digging around and looking how it works Joodr will be using a profile as node system using content profile. The main reason for me choosing this is how the data is stored when using core module and when using profile with CCK . I found profile with CCK is much better. There are other reasons too but overall for a SNS to be as scalable and configurable as possible content profile would be better, for smaller ones core profile should do just fine.

So i will be finally using content profile as profile module for Joodr.
