I have an 07 990 Adventure and my girlfriend has an 2012 F800GS. When I walk into the garage I can ride either bike and I always choose my KTM. The BMW just seems soul-less to me, it has no personality. The KTM seems like a purposeful built tool. It's kind of hard to describe and I am not doing a good job of it, but I can tell you, if you go with the KTM, you will never regret it.
You don't even want to know what the Gobbler is...
