I don't think there is such a thing as the ultimate modeler, as everyone has their own particular needs that have to be addressed. For me, I can't say enough good things about Rhino. It has a few limitations, but there really isn't much that can be modeled with Rhino's NURBS. As for polygon modeling, I've been dabbling in Wings, and it pretty good. A lot different than Rhino. When I have some time I'll read a few tutorials to get a better understanding of it. Rhino has a CAD feel, Wings a sculptural one. As for a jack of all trades I'd look at Lightwave, Cinema 4D or 3DSMAX. MAX is the only one I have experience with and I like it, but it is expensive. I'd like to purchase it some day. Hopefully someone can convince me that Lightware or Cinema is just as good.
