I haven't used Uber, but I have used Lyft. I wouldn't trust these drivers' ratings. My experience is that the conditions of the cars are generally better but about 20% of the time a driver will be at the wrong spot for pick-up. I've had to cancel and demand a refund way too many times. Also the driving isn't any better than the taxi drivers' I've had.
On the other hand I can get a new, clean, well-maintained and current-year car to myself for an entire day from a rental company for a 25% premium (inclusive of all the taxes and fees) on the cost of a round-trip Lyft between my home and my commute train station. When my family travels the weekly rate on such a vehicle is only about the equivalent of 7-8 such round-trips. That's an incredible value, in my view.
