I agree with just about everything said here. If you're mainly exporting into Bryce, keep P4. However, if you want to take advantage of all the new features that don't export, get P5. It can be a real pain sometimes, but the fixes are getting better (the rest of us have beta tested to death for free). And the new features are pretty neat. I still export to Vue or Bryce once in a while if I'm not using any of the new features. But if I want really nice hair or dynamic clothing, I just do everything in P5.
