Uber is basically the McDonald's of hired transportation. There are limitations, the experience definitely isn't premium, but its ultimately a fairly consistent purchasing experience that works most of the time.

Regular taxis? Sure, download this city specific app. Or one of the two city specific apps. Or call one of the local cab companies and find out you picked the one that doesn't consistently dispatch to your hotel so you end up waiting around with zero feedback. Or maybe you call and they show up in five minutes and its great.
