skinny controller or skinny model?

Thanks for your input guys.

Well I guess this is what I'm thinking right now.
The Fat Controller & Skinny Model is best for intermediate CI programmers.
The skinny Controller & Fat Model is best for Advanced CI programmers.

Anyway this is my opinion as I saw more advanced CI programmer using the skinny controller & fat model.
Maybe in my next project I'll try the opposite method.
And to observe which is much more convenient to use.
