This might be the wrong place to ask this, with so many people being airhead GS converts. I'm noticing how much money a decent GS fetches on the market, and I can't help wondering, what do you get with one that you don't get with a current thumper? The obvious comparisons would be with the Suzuki DR650 and the Kawasaki KLR650. The horsepower on the thumpers are down by a few hp, but the weight is down by 50-100lbs. Seat heights are similar, as are the wheel sizes. However, a GS in good shape is close to twice that of a used recent thumper. How do they compare in areas such as comfort, off and on-road capability, reliability, useable power, etc?
