Tata neu and Amazon are good general purpose cards. You can use Amazon pay balance and tata neu coins for a variety of purposes. Amazon pay balance even for bill payments and utilities.
But tata neu coins for grocery purchase, flight tickets and gold purchase. I use neu card often. Other than that, like mentioned above, for 10% cashback I use Swiggy card sometimes. But the net effect is not very visible apart from the fact that each month we get some cashback in the statement. But the only drawback is that it doesn't bring a visible change like a free hotel stay or flight ticket.
