I have Pioneer account since last 2 years and below pointers made me move from HDFC to Indus.
1. Metal Debit Card -> Gives good cashback, Domestic Lounge access, Zero Forex charges and metal card looks good and has premium feel.
2. Better Interest rates -> Savings and FD interest rates are better than HDFC/ICICI.
3. Custom Account Number -> You can customize your account number - 15 is prefix for Savings accounts followed by 10-digit number of your choice.
e.g. 15-1234512345 - I used my mobile number as 10-digit custom number, and this made it very easy to remember.
4. Locker - I got locker at zero rental after 7 months and with some follow ups were needed.
5. After knowing IQ level of RM (most RMs are same everywhere) I decided to deal directly with BM and this made my life very easy.
If not Indus, then I think HSBC is a good option provided you meet their premium account criteria.
I recommend going with Indus provided you have some tolerance to deal with their customer care or you make connect with BM and everything will be sorted.
