I say C4D all the way,the learning curve is relatively shallow compared to Max or maya.In fact I've been so into it lately I havent even made a pic in bryce for a month or 2 now.The whole modeling aspect can start to eat up your time in new ways.Instead of thinking"can bryce make it?",your attitude becomes more"now that I made a (place cool object here)" now its time to make it cool with tons of details bryce could never do.heres a plug type thing I made in about 20min in C4D,a simple object made a bit more advanced(its a plug of some type).Anyways I'll stop blabing now.
