How is the launch of Uber / Cabify in Mendoza?

Uber and Cabify, for a lot of fanfare 🎉 have (very – October 10, 2018, according to this article) recently launched in Mendoza.

I will visit next month and I am curious about the option of trusting Uber to jump between the holds instead of bothering with other means of transport.

The above articles seem to me essentially press releases; Can anyone who has recently visited offer any empirical advice regarding:

  • Availability / waiting times: can I find drivers? For the whole day? In the south (Lujan de Cuyo / Uco Valley)?
  • Prices and competitiveness: how are the rates and how are they related to the private rental / taxi?
