In a direct head to head comparison of geometry, the Specialized Demo and YT Industries TUES are not all that different. They share the same 63.5 degree headtube angle, and the reach, chainstay, and wheelbase numbers are all within a few millimeters.
The big surprise is just how different the suspension kinematics appear when using simulation software to compare the anti-squat, anti-ride, pedal kickback, and leverage characteristics of both frames. Of course, we can speculate over charts and graphs, but the real test will be to see how well Aaron Gwin adapts to the new bike this season.
