I lost my Kotak Mahindra credit card. What is the fastest way to block it through the app or customer care to prevent misuse?

I had the same dilemma. The way I decided was: list down my top 3 monthly spend categories, calculate the rewards on each card, and pick whichever gives the highest cashback on MY pattern. Generic 'best card' lists are useless for personal decisions.
The customer care experience matters more than people think. I've had two cards with similar rewards, and the one from the bank with better support saved me ₹18,000 when there was a merchant dispute. Don't underestimate this.
Two cards from the same bank usually share credit limit, not stack it. So if bank gives you ₹2 lakh total, splitting between two cards doesn't increase your available credit. That's a common misconception people carry when applying for their second card.
