I like Genesis, and V5.  Like Vilters said, though, I have WAAY more stuff for V4.  Additionally, even with the DSON, which is pretty bloody cool; setup time for a scene is incredibly long, clothes don't always transfer from DaZ Studio properly, and I can simply get things done faster with V4.  One thing I have found with 3D in general is that it is very time consuming, no matter what program or platform you chose to use.  Fun though!
