http://www.dpreview.com/lensreviews/olympus_m_9-18_4-5p6_o20/

According to dpreview the image quality of the Olympus 9-18mm lens is more or less on par with that of the Panasonic 7-14mm. The Olympus lens costs and weights less but the Panasonic lens has a better build quality, a wider angle and constant f/4 aperture.
