I owned a GW680III ('till it was stolen!), and I really loved it and will buy a replacement one day. It is a nice modern rangefinder - comfortable to use, with a great lens. It looks fairly normal until you see it "to scale" with a 35mm camera of any description... I actually preferred it to the GF670/Bessa III because of its very manual nature and the certainty of shutter action ("click", rather than "did I actually press the shutter - I can't tell?". I would rate the lenses about the same really.
