SBI is India's most trust worthy bank. It is a government bank, so no need to worry about the closing and lifting away of money. The policies of bank are also good like the life insurance policy, etc
The only con of SBI banks is the poor customer service. The employees of the bank are govt officials, so they neglect customers . The Condition of SBI ATM's is also bad when compared to other private banks.
Thats it, if u want reliable bank, then go for SBI . but only if u dont care about customer service
