I have account in state bank of india since last 7 years and I must say state bank of india is really very good.till now I have never faced any problems from this bank. Like my refunds for any cancelled orders usually comes to me within the stipulated time.
They also provide a high rate of interest on the savings account as compared to other banks and very recently they have also started many programs of investment like TDR etc.so I think its a quite reliable bank and its really good from all aspects.
