How to dispute a wrong transaction on my credit card

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.

I've owned 4 cards over the last 7 years. The biggest lesson: a card that fits your spend pattern beats the 'most rewarding' card on paper. A 5% cashback card you actually use daily will give you 10x more value than a 10% card you use once a month.

Forex markup comparison: Amex = 3.5%, HDFC Infinia/Diners Black = 2.0%, Axis Atlas = 3.5% but with milestone fee waivers, ICICI Emeralde = 3.5%, Standard Chartered = 3.5%. If you travel more than twice a year, the math favours Infinia or Diners Black.
