You should consider getting the UOB one card, consolidate your recurring payments and cap it to $500 to earn the first tier of cashback, while the remaining payments, you divide to whichever card gives you the best cashback or rebate depending on your type of purchase 😊

HSBC advance card is not an unlimited cashback card. They have a cap on the cashback per month, even for advance banking clients. Plus, if you are not an advance banking client, you would not get subsequent card fee waiver if you do not spend at least $12k a year. Citi SMRT card is also good but its not actual cashback as in real cash credited to your account. The rebate comes in the form of SMRT$ which is a rewards program. Some people prefer to get actual cashback credit rather than collecting rewards points.
