I'm pushing Carrara. The modellers are functional, the render engine is excellent, the price is very reasonable. But more than all of that, the thing is easy to use and just feels very friendly. Maybe that's just four years of Ray Dream speaking, plus enough Bryce to get over the Kai interface hurdle. But I think Carrara is mostly pretty clean and simple. And not a small point -- it renders so durn fast it gives you a lot more willingness to experiment there.
