Jio users in my point of view biggest netwirk in short time period is jio.because of Volte voice over concept is applied in this network.
Then big advantage is high speed internet 4G LTE long term evoluation process in jio service and every problem are suddenly get action in short period.
Low cost offers also available in jio.
3 month, 6 month, 1 year and there have more bulk of offers low coat .
All the networks reduce the cost of internet because of jio .
