Preferred model approach - instantiated or not?

I started off my experience with ci using the second approach you listed. I have since switched to the first approach and I don't think I could ever go back. Using this approach makes my models feel more streamlined and consistent I do agree with your statement that coding each model was tedious(yes, was). I eliminated the tedious coding of the models by creating this handy little tool that generates my models for me.(shameless plug)
