The BMW's are nice, but the BIG deciding factor for me happens when you mash the starter button. The BMW sounds, umm, kinda cheesy to me. Really lame, actually.
As far as ergos, comfort, etc... I think the Goose is fine. Of course with any bike, it takes a little conditioning (and some rubber hose on the foot pegs) before your body will allow any real mileage. Personally I've covered 10,000 this year with no real problems, and range/reliability has been great. Around 75-85 mph on the highway gets me around 170-180/tank, and that number goes way up if you drop the speed down to around 60.
It's all wind in the face, after all, but I'm a bit partial to the LeMans in the end.
