I have been practically using almost all the radio taxis. Meru is a cheat. they will silently allot you same model cab with higher rates and also charge you extra for peak hours. They dont resolve the issue & make you pay up higher fares. Rates are also high.
Ola cabs metering many a times is not correct.But they do resolve the dispute. Better than Meru. Tabcab has few taxis . rates are higher.
Taxi for Sure is much better than all the above but their drivers are not sophisticated enough. The no. of taxis are also not sufficient.Difficult to get their Cab. Rates are reasonable.Customer Service & Cabs average. They offer 3kms for 49/- which no other operator offers.Good but of they can professionalise more, it can do wonders.
Uber does not have many cabs. Prior booking not possible. Rates are also high. They compulsory want to deposit sufficient balance in your Paytm A/c or give an authorisation to debit your credit card. This is extremely Bad.Not recommended at all.
