I have the following:
Mbb Amex / visa platinum
Mbb Amex reserve
Mbb visa infinite
Uob yolo visa
SCB visa
Alliance / OCBC titanium master
Big pay
Reading thru the posts here, looks like bigpay is best (1% + best rate)?
Second is my Mbb Amex premier up to rm1000 spending on weekends for rm50 cash-back + treat points to offset 2.5%+rates ?
Third is Amex reserve for treat points conversion offset 2.5% +rates?

These 3 ambank cards have 0% foreign transaction fee.

1. Ambank True Card
2. Ambank M Card
3. Ambank Bonuslink Card

All other ambank cards have 1% charge.

And I'm personally using Ambank Bonuslink.
