I am not an EI user at all but I have worked as a modeler at three different studios and have to say that if you want the best Sub D modeler in the world use MODO without a doubt. I use a combination of Modo and Zbrush and all is well. I really couldn’t ask for more.
I have been asked to Model professionally in Max, Lightwave, and Maya, and without a doubt my current Modo, Zbrush combo is far far superior. Modo is the base Zbrush for Zbrush things. Adding realism and small details basically. \
If I couldn’t use Modo, I would choose Lightwave’s modeler. It’s thourough, complete, really fast, and battle tested. Plus the whole app is so cheap now that you get the animation tools and a pro renderer for free. The modeling tools pay for themselfes. Also Luxology has announced a new Modo render that looks very promising.
Just my opinion.
