Which is the best and worst bank for opening a NRE/NRO account in India?

Since now days every branch of same bank is connected via intra-bank networking, you can go to any branch and more often then not you can perform transactions, check balance, update address, telephone or mobile number, add nomination and can do several other tasks. Of course you can do most of them online and some of them offline by downloading form and courier to respective branch, some time it's quick to visit a branch. This accessibility is actually main reason why some one wants to open their NRE account on banks like HDFC, ICICI and SBI bank.

HDFC is one of reputed Indian bank, after ICICI and SBI, and their services and support are good quality. Unfortunately HDFC bank doesn't offer interest rates compared to YES bank, but it offer some good features and given it's accessibility you can also consider opening an NRE account in this bank. HDFC has very good online banking site and their customer support is also great.
