No, I do not find the XT6 to be exciting, but I am not its target market. I also do not like the styling of the Lincoln Navigator and Aviator. But to me, there is no mistaking any Cadillac for anything but a Cadillac. Take the Lincoln badge off and you are left with a hodgepodge of borrowed styling cues. But these are my opinions, apparently your way of thinking is a fact.
And I'm not sure what of Lincoln's product is better. What is out there isn't selling any better. And certainly you aren't telling me vehicles that no one has driven yet are better.
And using the Continental/CT6, yes, the market is small. However, if the Continental is so superior, it should still outsell the CT6 by a decent margin, albeit low volumes.
