Panasonic Lumix DMC-GH2 or nikon D7000

Any one out there has experienced both these cameras?

I know the GH2 is a 2x crop and the D7000 is a 1.5 crop. One advantage is the lightweight Gh2 and lightweight lens 14-42 and 14-140 lens (35mm equivalent of 28-84mm and 28-280mm). How is the image quality of the Gh2 or Gh1?
Love to hear comparisons on these 2 cameras.
