i have it for maya and cinema 4d --

personally, the render engine is stronger with maya than c4d.  however, the c4d integration is very much less buggy.  the opengl in Vue works better in cinema4d than it does in vue!!!!  opengl doesn't work very well in maya either.

now if that doesn't matter to you maya has much longer rendertimes but much better final quality.  with that said, i have been working with cinema4d b.c. its less problematic has very good open gl support and figured i could just do post processing work and use vray for my renders...
