We prefer Hwy 20. More natural beauty. Like Twisp, Winthrop, Diablo, New Halem....
To be picky, none of the listed places are entirely natural. Twisp is a town of shops and motels. Winthrop is a Western themed tourist town. Diablo is a reservoir, one of 3 that tamed a wild river to give Seattle electricity. Newhalem was the company town, headquarters for that dam project.
Winthrop is a pleasant stop. The dirt roads to the east of Twisp/Winthop are interesting in suitable vehicle. Views over Diablo lake are impressive. Colonial Creek Campground looks like a nice place to stay, though I've only made day visits there. There is nice camping near Newhalem, pretty rock gardens behind the power plant, and a nice forest walk across the river to a smaller power plant.
US2 also has a themed town (Leavenworth), a lake (Lake Wenatchee, with state park and forest service campgrounds), a scenic mountain pass, old growth forest walks (Deception Falls rest stop), historic railroad trail, trailheads for longer hikes.
