I am an Airtel user and use it simply because its Airtel. Also, wherever I am in India, my window always shows Airtel. As far as customer orientation is concerned, none can touch Hutch. They are in a totally different league but my need is accesibilty and reach. I have my wife and son using Hutch and they swear by it but that is probably because of the percieved brand value. If you ask me and if we go tech neutral in the mobile telephony space, it should be Airtel v/s Reliance. There you are comparing two service providers with comparable subscriber base, reach et all. And there, Airtel wins hands down. True Reliance took away the mystique of mobiles and made it affordable for everybody to own by setting standards (price) and constantly lowering the entry barrier, but this was done at the cost of service. I used a Reliance too, but gave up in disgust! For me, its Airtel all the way!
