Well said Cyath,
All manufacturers and models have a different idea on "What" makes their bike better than the competition. IMO,, BMW started the so called "Adventure" market.
But how many of us rode or borrowed a friends old briggs and stratton 5 hp mini bike out in a vacant lot somewhere near our house? At the time, that was "Adventure" riding to us and we loved it. For some of us, it was a very long time ago, long before any bike manufacturer even conceived the title of "ADV Bike". Now they all have one.
So the burden lye with the end user,,, Which model/make to ride home on. However, some machines will put a much larger smile on your face than others. Take it from a guy who used to ride a 650 V-Strom.
You just can't make comparisons between certain bikes. The only thing they have in common is the fact that they both have only 2 wheels.
