Well, depends on the needs - I guess. As there are specific cards for fuel, travel, dining etc.
In terms of simple rewards calculations that I have is Axis Ace, which gives 5% on bill payments/recharges via Google Pay and 2% on all other rewards. It also has 4% on some other platforms like Swiggy, Uber etc. You might get better cards for swiggy, uber alone, but a general 2% on all in Axis Ace seems good for general purchases. It does have a catch - need to spend 2 lakhs in a year for no annual fee (of 499).
