While right offers better views during Des Moines departure, left provides superior scenery for the majority of the flight and especially on approach to Portland, where the Cascade Range and Willamette Valley dominate the view.
Flight Path
You'll cross the Missouri River (Iowa-Nebraska border), then the Great Plains of Nebraska and Wyoming. The Black Hills appear on the horizon in South Dakota/Wyoming (far left/north of typical flight path). As you approach Oregon, the Blue Mountains become visible, followed by the Cascade Range. The Snake River valley in Idaho and the transition from high desert to the Willamette Valley are notable midpoint markers.
