I'm 6'6" and 265. I love the dual sports because they typically just fit. For a noob please consider the DR650, XR650 or KLR650. A big single that's designed for on and off road fun will help you learn how to manage a bike without the weight and power of a road bike to help you get into major trouble. Also, if and when you drop one of these off road you're not looking at major expenses for repairs. Once you have more riding experience then you should be able to make up your own mind about what direction to go.
