Nebraska is way worse than Kansas in terms of seeing absolutely nothing. I-80 from Kearney to Ogallala is legitimately the worst drive in all of America in terms of boredom.
I typically go Wichita to Salina, then Salina all the way to Denver if I'm in a hurry. It's a long route, but you have a stop in the middle around Liman. The best route (in terms of most to see) to get up to Yellowstone is actually going along the old Oregon trail route through Ash Hollow NE, Chimney Rock @ Scottsbluff Nebraska, Ft. Laramie in Wyoming. If I'm not in a hurry, I typically skip Cheyenne altogether.
