In your scenario, assuming salary credit, bill GIRO and cc spend all met, Maybank is still better. The problem is that UOB interest rate is just not competitive, especially at lower deposit balances.
UOB (1.75% @ 20k): annual interest earned is $350.
UOB ONE card ($500 spend every month): $50 cash back per quarter for total annual cashback of $200
UOB total annual: $550
MBSU: Blended rate (cos different base rate for first $3000) gives you total annual interest of $598.13
MB CC: $500 spend each month gets you $30 per quarter for annual total of $120.
MB total annual: $718.13.
The only bad thing I'd say about MB (other than the fact I think UOB IB interface is probably better), is that the GIRO bill requires $300 and cannot be offset using the MB CC bill. So you have to spend $300 extra, in a sense. If you can meet that, then fine but not everyone can. For UOB, you just need three GIRO bills of which the UOB credit card GIRO counts too.
Let me know if the numbers checks out and sorry for the earlier erroneous reply to your question. I personally haven't decided whether to go with BOC or MB yet but UOB is not the front runner for sure.
Wealth Farmer, quick question. I have no idea on how to go about counting.
Say 20k in account. Spend 500 per month on CC. Able to fulfill all criteria to get saving account %. Which one will be more profitable?
UOB One card + UOB One (1.75%)
or
Maybank Platinum + Maybank Saver (2.9%)
