Recommended pickup locations -> No longer door to door?
Assigning next rides before the previous one has completed -> No longer "feeling like a baller" while your driver is fielding calls from other customers with you still in the car
Wait times have been getting demonstrably worse all over Manhattan, probably elsewhere too
General quality of car/driver has been in decline since Uber started, in part precisely because of their putting cabs out of business. What's your cab driver going to do when he decides it's not worth driving a cab anymore because of Uber? Duh, work for Uber.
There's no comparison right now, but there will be soon.
I'm never going to use Uber again except for business travel due to their nice tie-in with business accounts. Personal travel? Nope. In NYC I use Juno and elsewhere I'll use Lyft, Hailo, or any number of local alternatives.
