Which credit card gives the highest cashback on online shopping?

Short answer: no, EMI on credit card is not cheaper than a personal loan for large amounts (>₹50,000). The processing fee (~₹199-₹599) plus the interest (~14-16% reducing) usually adds up to slightly more than a personal loan rate of 11-13%. But for small-ticket EMI (₹10-20K), it is fine.

Honestly, the annual fee is on the higher side. But if you spend consistently on the accelerated categories, the cashback more than offsets it. I did the maths on my own statement last year and came out ahead by about ₹3,200.
