I think the benefits of Priority Banking are:
1) Cut Q - its not super extraordinary or anything, but given a choice everyone would like it for free.
2) Higher interest rates - The most competitive interest rates are usually given to PB customers, be it FD Promo or PB account. Again, its something that everyone would like to have access if they can have it for free.
3) High level credit card - if you travel a lot, this can be very useful for you. Usually involves free lounges in airport, bonus points as compared to ordinary card etc.
I think you shouldnt just leave money at the bank for the sake of attaining PB, but money is a good tool and option to have, in addition to the additional perks of being a PB.
For myself, while i am waiting for the right investment opportunity, i am much better off with access to PB rather than not. If i am stuck with ordinary accounts, I make less money on my money thats sitting in the bank anyways. And i have to Q during rush hours. While I see nothing wrong with Q-ing, I certainly wouldnt mind a free walkover to the counter either.
So yeah, ultimately your financial goals should have no correlation upon attaining PB or no. If you can use the money right away for business, great. But not everyone wants to use the money right away. There are times where its a lot better to just wait on the sidelines for a good opportunity, and that usually involves a lot of patience and waiting.
But, if your financial goals happen to coincidentally work along with side of PB, theres no doubt you can make good use of it.
Which bank are you with? Do you have any bank which you would recommend for PB? No specific service I am particular about. Mainly for the reasons you mentioned above. Thanks.
