What should I be comparing when I am deciding whether to get the AMEX Rewards Card or SC Rewards+ credit card?

You would have a few deciding factors to consider:

• Annual Fees (and the possibility of waivers)

• Credit Card Benefits: think cashback, miles (can we fly soon?) and other rewards

• Sign Up Incentives/Bonuses

• Acceptance (eg acceptance of VISA compared to other providers like Master Card, AMEX, Diners Club)

and for me, I also factor in the user interface and user experience of an issuing bank's mobile app as I have to deal with them to facilitate my card use and spend.

Off the top of my head, I can think of a few factors:

• Any sign up bonuses? (amex cards typically have quite generous signup bonuses)

• Miles earning rates (am assuming you are looking at the amex krisflyer or ascend card, 1.1MPD & 1.2MPD respectively. Not too familiar with the SCB card)

• Annual fee (which is cheaper?)

• Usability (VISA is more widely accepted than AMEX)
