Which is the simpler miles card: UOB PPV or HSBC Revolution?

I am choosing between these 2 cards for my personal spending card.

​

(My wife and I have the Citi Rewards/Amaze & DBS WW card for joint expenditure, which we prefer to keep separate from personal spending. This works for us for tracking purposes.)

​

Personally, I already have a DBS Altitude, as a general spending card. I'm looking for a specialised spending card and am ok with foregoing some miles in view of simplicity.

My thought process:

​

UOB PPV: $5 earning blocks and UOB$ merchants are cons; I use 7-11 and Giant quite a fair bit, and often have smaller purchases

HSBC Revolution: wide range of covered categories for contactless but I'm guessing no bonus points for the miscellaneous spending like...stationery/dentist/etc.

​

Are there other factors I should think about, like customer service?

​

Which of the cards would you suggest given what I've shared? Thank you!
