Personaly, I find sub-d modeling far easier and more effective in the long run.Sometimes in Zbrush I would sit around and tweak endlessly because I couldnt just ...you know, select the points/poly faces and put them in a proper arrangement right off the bat.There is no such thing as good poly flow in Zbrush.It doesnt really matter if you are only using the high rez models to make a displacement map, but I found thats almost the only reason to have Zbrush.Which I fould out I can do just as easily in Photoshop(by painting a disp map over a UV map) or do it directly in C4D using BodyPaint(in real time).You can do that stuff in Maya if I recall as well(although..not the PLE version).
