A little bit late in the game here and no offence for the comments, however these "this app vs. that app" comments are pretty pointless and only get people riled up for no reason. What matters is how YOU feel using the tools that YOU feel are best suited for YOU to get the job done.
I was doing architectural illustration for a while using C4D and I couldn't believe how many people relied on Autodesk 3DS Max and Vray. C4D's native renderer and the price for the kit is hands down way better and cheaper than the 3DSM/Vray combo. But that is only my opinion. And I guess that is the point. Who cares what you use as long as at the end of the day you are proud of what you have created and your clients are happy....
