I am imperia customer for almost an year. There is nothing special man other than basic things which I have used
Not so good benifits
1. Free cheq to cash withdrawal
2. Free atm withdrawals
Good benifits
1. Got free locker
2. Got marriot bonvoy LTF
PS: one advantage I found of having account in sbi and hdfc is their branches are available everywhere, tier 3 and even village me I have seen hdfc branches. Whenever have to fill cheq if it's in same branch then cleared very fast and even if signature donot match u can visit branch if payee and payer branch is same. So many people have accounts in hdfc hence become easier in cheq things
Though all above are from my personal opinion and personal use case, and the reason I am holding imperia account in hdfc and not any other bank rn
Thanks for reading
