I have compared the differences between the UOB One Account (which current advertises up to 3.33% p.a. interest rates) and the OCBC 360 Account a couple of years ago. Even with the changes that the OCBC 360 has introduced over the years, it is still one of my preferred savings account in Singapore since I can achieve up to 1.85% p.a. of interest (you can earn up to 3.05% p.a. interest if you insure or invest with OCBC), up to S$70,000 fairly easily. The UOB One Account will be introducing some changes from 01 August 2018 and they are quite lucrative (especially if you already use a UOB One credit card which gives you cash rebates) but it may not necessarily be convincing enough for me to make the switch.
