Panasonic 45-175mm X or 45-200mm

I have a GX1X on it's way to me with the 14-42mm X PZ lens. I would like to have a long zoom for my second lens. I am looking at the Panasonic 45-175 X lens or the 45-200. The X lens isn't that much more money and I could afford it but is seems people are more fond of the 45-200. Perhaps because its a better value or more of them are out there. I have read reviews on both and seem to find more reviews on the 45-200. What are your thoughts? All input is appreciated.
