SC Unlimited Cashback CC or SC Spree CC?

It depends on your total spending AND how you pay for things.

For me, I spend around $700/month.
Spree is good if:

• you pay using applepay or other mobile contactless (which will earn you 2%)

• you spend less than $3000/month because that's when you'll hit the $60 cashback cap.

Unlimited is good if:

• you spend more than $4000/month because the unlimited rebate on all spending
  Both cards have no minimum spending, which I love.

Personally I use Spree cos it's a higher cashback. For big purchases I will use Manhattan. So the unlimited cashback to me is like not here or there haha
