Salary account or Savings account?

Hi folks I am failing to understand what is the advantage of talking Salary account. Even the thing about maintaining zero balance doesnt convince me. Recently I visited Axis bank and i was told I have to maintain 25k min balance or transact minimum 25k to avoid penalty. So lets say I have only 25k in my account and I took it out ,it counts as a transaction and I wont have to pay penalty right? Then whats the point.

If interest rates is the difference I want to know how significant it is and any other benefits ,which one is suggested for a salaried employee

Thanks in advance
