Must just be due to the criteria the US Army used. The BO105 looks like a brick compared to the others in the very good half.
Having read up on the G2 my only comment would be usability, MGW is 700kg, empty weight is 420kg, so doesn't leave a lot (280kgs). On their website they show a woman putting a load of luggage into a G2!! If she is like my wife the pilot would have to weigh 30kgs!!
