Lookout is out "wow" because (westbound) you are driving on the edge of a very spectacular drop-off...

Compared to some Washington grades it isn't that 'wow' (I90,US2,I82). Still you can see a long ways out into the valley while focusing on controlling your speed. There are trees on the slope below, and a paved shoulder plus Jersey Barrier the whole way down. There is a runaway truck ramp 3 miles down, plus a couple of other viewpoints further up.
According Idaho DOT, max grade is 6%

There are couple of alternatives that don't have significant passes. MT/ID200 north of Missoula follows a major river valley into Idaho. US2 crosses the Continental Divide south of Glacier Park via one of the lowest Rockies passes.
