I rather agree - in that the Carrara way is not very intuitive. But in the end it's down to what suits you. Amapi is an odd fish in that it is trying to be accessible to those new to modelling as well as be a high-end app. At least you can customize the interface pretty much how you want. And Amapi Pro's capabilities are pretty awesome. It will be interesting to see where Eovia takes it and Carrara. I wouldn't be surprised if they build on C's strengths in rendering and scene building, rather than modelling.
