Cabs/Ubers/etc are too expensive to use daily, but for a one time thing (such as flying into an airport), it's so much less stressful than trying to deal with public transportation.

I'll give an exception to certain cities that have superb transit options, but none of those cities are in the US.

The transit option between SeaTac and Downtown Seattle is superb. I admit it can be improved (e.g. you have to walk through the parking garage to the station, and it is a bit slow going through Rainier valley) but for 2.50 USD it is the best option going from SeaTac to Downtown.
