POVray is a pretty good renderer. If you want to see what can be done with it, visit www.irtc.org - most pictures there are done with POV. But if you use POV you will have a different set of material option and a different set of lighting options. PoseRay is great as a bridge to POV. But it cannot do everything perfect. Some handwork is required, if you want to get the best out of POV.
