The perks aren't great for someone with good card(s) already. Actually, they aren't great to the marginal consumer (who doesn't have any cards yet) either. Square's Cash App card gives 10% off at Trader Joes/Whole Foods/Kroger plus discounts at a host of fast food places, and can be gotten by anyone, even without a bank account or credit check or anything. The downside is its a debit card, the plus is that the rewards compete with A+++ credit cards.
