Uber cab I can surely say is one of the best and safe cab service in bangalore right now. They are very professional and offers very good rides. I agree that there was a Delhi incidence which tarnished their image. But after that they are very strict on driver verification process. Their service is very cheap in banaglore right now up to 15km range. Prices per km doubles after 15kms. If you are travelling more than 15kms you can opt for taxi for sure or ola.
Pros: cabs are new and neat. Drivers are very presentable. Very professional service.
Cons: not preferable for more than 15km travel.
