In rasterization you (essentially) do a mathematical projection of objects onto the screen and then calculate the lighting of that object base on its relationship to the lights in the scene. This means that the contrabution from other objects (like shadows and reflections) are not handled and you have to produce hacks to get these effects.
In recursive ray tracing you trace a line from the screen into the environment to trace the light from the environment throug the screen; as a result you get very high quality reflections and shadows. In general it is a much (MUCH) better simulation of light which results in much higher image quality.
