If the services are pretty much equivalent, and the only thing left to compete on is price and/or some vague elements like experience, isn't this basically a textbook case of commodity?
The pricing depends on Surge and Wait times and is pretty volatile - both of them are experimenting. I see a 10-15% shift in the Bay Area - with the win going to one of Lyft or Uber randomly. I agree with Farhad - I use the two services indiscriminately. As far as "Better Experience" - Many drivers in the Bay area work for both services, and some previously worked for Lyft and Moved to Uber, and Vice Versa.
Long term - it really depends on how committed each service is to responding to User Feedback, and managing the drivers with consistently low scores out of their system.
