Icici has these categories of account in increasing order. Regular, Privilege, wealth management, wealth select and Private.
Talking about top 3 categories - Wealth management gets world debt card. Wealth select and Private gets visa infinite.
All these cards are lifetime free. Looks of visa infinite is better. And the only extra benefit in visa is few more lounges.
The best benefit in these accounts is very helpful RM (though he/she also has targets to sell) and instant connection to wealth customer care on phone banking. People are polite and nice to talk to. At the branch you walk into the dedicated wealth section and they help you out with everything. Products like loans are available at better rates.
If needed they go out of the way to help, can even come for doorstep services. Very friendly and helpful people.
They would spoil you. Just to share an example, my wife drops into the branch just to say hello to them. She has made friends at the branch.
The benefit of wealth select and private is more to people who make investments. Otherwise all 3 types of acounts are more or less same.
The downside is regular calls and advices to sell products.
