I've been using Uber and similar apps for years mostly in Europe and Asia and 80+% of the time the price would be substantially cheaper than taxis (often 50% cheaper in places like London). They use dynamic pricing though based on supply/demand so it is very possible to have higher price than taxi based on parameters (i.e. if you booked a ride in central Paris during rush hour the price would spike up). But from my experience you cannot use those anecdotes because if you use Uber a lot (like hundreds of rides) you will statistically see they they are cheaper in big majority of cases.
