Lens Civil War: Canon 18-200mm vs the two kit-lenses facilitated by 500D/T1i

Japanese website DC-Watch has conducted a Canon Lens Civil War with the Digital Rebel T1i 500d Kiss-X3 being the facilitator. They try to answer the eternal question, should you get a superzoom lens or the two kit lenses? In this instance, the question is between the 18-200mm EF-S IS versus the 18-55mm EF-S IS and 55-250mm EF-S IS.

The text is computer-translated but the pictures speak for themselves. They have lots of pictures, available as full-size downloads and they close their article with a giant table listing the superzoom lenses of the different mounts. [lens reference alert!]
