Besides these 2 advantages, you have the lower Enrich airmiles conversion rate. But you lose the 5% cash back on weekends? Doesnt seem a fair trade off. Im on the Maybankard Platinum Amex. Was thinking of upgrading but doesnt look enticing enough.

Btw, my Maybankard Platinum Amex got hacked last week. Few US transactions. Got it blocked and cancelled immediately. But last night again another transaction this time for AirAsia. Used HSBC credit cards for 10 years and not once had this issue
